Vacuum cube - manual Dear Customer, You will have lots of fun with latex cube you have just received. However , there are some rules , which need to be adhered to in order to operate it safely.

We have prepared few tips for you. Please read them before you use the cube. It is very strong bondage device and you may not be able to get out without help from outside , if anything goes wrong.

Whenever this signal is used , partner on outside should immediately release the vacuum and help you to get out.

Before first use , wash the latex sack with soap and water on both sides , let it dry and then apply latex polish both on inside and outside.

Because the entry opening is small , you need to assemble the frame inside the sack. All parts of the frame are inserted inside via the entry opening.

It helps to lubricate the pipes and the inside of the sack with latex polish do not use talc on inside of cube - it may cause valve malfunction.

Using the aluminium rod , roll up the latex tunnel. Take care to roll it up tightly and without any wrinkles , which may cause air leakage.

Then , secure the seal with supplied clamps. Make sure to use thick stripes of latex to underlay under the clamps - this is to protect latex sack from any possible damage by clamps.

Ask the person inside for permission to turn it on. Only then turn the vacuumcleaner on. When the air is completely evacuated , disconnect the vacuumcleaner from cube and then turn it off.

If you turn the vacuumcleaner off , while still conneced to cube , some air may get back into the cube , because for proper function , the valve needs sudden pressure change.

Then let it dry on dark and cool place. After it dries on one side , turn it inside out , so both sides can dry. There must be no bubbles coming out of it.

If bubbles do come out , try running some water thru it , let it dry completely and then put few drops of silicone oil into it from the narrow side.

Our goal is to deliver easy-to-use process control and data visualization. When new equipment needs to be added, modularity allows easier integration of chambers into overall system design.

Our team sorts out integration issues before equipment arrives on site for installation. Chamber behaviour can be predefined by the programmable logic controller PLC.

The PLC controls the vacuum pump and lighting, evaluates temperature and signals from pressure gauges, and much more.

While working with fragile materials or limited samples, tracking of vacuum parameters allows for better process control.

The programmable logic controller PLC can be managed via a web browser which can be opened on any device with an access code and WiFi connection.

Our custom control embedded system suitable for complex assemblies allows equipment to work in conjunction with other systems.

The S-Cube configurator allows you to design and build vacuum chamber that specifically caters to your application. Create your own.

Need help? You do not need to finish your configuration. Send us an enquiry anyway. For the last three decades, we have gone from manufacturing components to offering turnkey solutions in the field of vacuum technologies.

Streicher Vacuum Technology. Every significant project starts with an idea. Complex projects have given us an understanding of the challenges faced by customers from various industries and research fields.

One of those challenges was the time-consuming process of developing an optimal vacuum chamber design for extremely demanding applications. Our engineers aimed to deliver a controlled vacuum space with possible modification throughout the course of the experimental procedure without the need to create a new chamber.

A 3D model is not generated for each configuration. A 3D model is sent to you after we receive an enquiry from you about the configured chamber.

After we receive an enquiry from you about the configured chamber, we send you a 3D model and drawing of your configuration.

On this drawing, you can easily specify flange position. There is a difference in the number of operating cycles based on material.

The maximum number of load cycles is affected by chamber size. Standard flange accuracy is greater than 0. This accuracy can be improved by 0.

The minimum dimension of the chamber is mm. The maximum dimension depends on wall thickness. Custom-made chambers can be up to a length of 6 metres.

We are flexible and offer custom solutions. Chamber of the same size can be connected in multiple directions with no limitations. A row or L-shape can be created or four chambers can be made into a square or eight chambers into a cube.

Limitations arise when dealing with chambers of different sizes. The view in the configurator is just to roughly illustrate the product.

We send an accurate render of the product after we receive an enquiry from you. This render is highly accurate and improves upon consultation with the client.

The configurator serves as a communication tool between our team and clients. It identifies problems early and makes communication more efficient.

No, it is not possible to purchase S-Cube online. Our team will get in touch with you to prepare a comprehensive price calculation based on your precise requirements.

The calculation will set out the preliminary terms for a purchase order. We understand that fast feedback is important which is why our teams contacts you immediately after receiving your request.

Related products. A few types of tube permit operation with the anodes at a dull red heat; in other types, red heat indicates severe overload.

The requirements for heat removal can significantly change the appearance of high-power vacuum tubes. High power audio amplifiers and rectifiers required larger envelopes to dissipate heat.

Transmitting tubes could be much larger still. Heat escapes the device by black-body radiation from the anode plate as infrared radiation, and by convection of air over the tube envelope.

Tubes which generate relatively little heat, such as the 1. Gas-filled tubes such as thyratrons may also use a shiny metal anode since the gas present inside the tube allows for heat convection from the anode to the glass enclosure.

The anode is often treated to make its surface emit more infrared energy. High-power amplifier tubes are designed with external anodes that can be cooled by convection, forced air or circulating water.

In a water-cooled tube, the anode voltage appears directly on the cooling water surface, thus requiring the water to be an electrical insulator to prevent high voltage leakage through the cooling water to the radiator system.

Water as usually supplied has ions that conduct electricity; deionized water , a good insulator, is required. Such systems usually have a built-in water-conductance monitor which will shut down the high-tension supply if the conductance becomes too high.

The screen grid may also generate considerable heat. Limits to screen grid dissipation, in addition to plate dissipation, are listed for power devices.

If these are exceeded then tube failure is likely. Most modern tubes have glass envelopes, but metal, fused quartz silica and ceramic have also been used.

A first version of the 6L6 used a metal envelope sealed with glass beads, while a glass disk fused to the metal was used in later versions.

The nuvistor was a modern receiving tube using a very small metal and ceramic package. The internal elements of tubes have always been connected to external circuitry via pins at their base which plug into a socket.

Subminiature tubes were produced using wire leads rather than sockets, however, these were restricted to rather specialized applications.

In addition to the connections at the base of the tube, many early triodes connected the grid using a metal cap at the top of the tube; this reduces stray capacitance between the grid and the plate leads.

Tube caps were also used for the plate anode connection, particularly in transmitting tubes and tubes using a very high plate voltage.

High-power tubes such as transmitting tubes have packages designed more to enhance heat transfer. In some tubes, the metal envelope is also the anode.

The 4CXA is an external anode tube of this sort. Air is blown through an array of fins attached to the anode, thus cooling it. Above that level, water or water-vapor cooling are used.

The highest-power tube currently available is the Eimac 4CMKG, a forced water-cooled power tetrode capable of dissipating 2.

The generic name "[thermionic] valve" used in the UK derives from the unidirectional current flow allowed by the earliest device, the thermionic diode emitting electrons from a heated filament, by analogy with a non-return valve in a water pipe.

In many cases, manufacturers and the military gave tubes designations that said nothing about their purpose e. In the early days some manufacturers used proprietary names which might convey some information, but only about their products; the KT66 and KT88 were "kinkless tetrodes".

Later, consumer tubes were given names that conveyed some information, with the same name often used generically by several manufacturers.

The first number is the rounded heater voltage; the letters designate a particular tube but say nothing about its structure; and the final number is the total number of electrodes without distinguishing between, say, a tube with many electrodes, or two sets of electrodes in a single envelope—a double triode, for example.

For example, the 12AX7 is a double triode two sets of three electrodes plus heater with a The "AX" has no meaning other than to designate this particular tube according to its characteristics.

Similar, but not identical, tubes are the 12AD7, 12AE A system widely used in Europe known as the Mullard—Philips tube designation , also extended to transistors, uses a letter, followed by one or more further letters, and a number.

The type designator specifies the heater voltage or current one letter , the functions of all sections of the tube one letter per section , the socket type first digit , and the particular tube remaining digits.

In this system special-quality tubes e. Some special-purpose tubes are constructed with particular gases in the envelope. For instance, voltage-regulator tubes contain various inert gases such as argon , helium or neon , which will ionize at predictable voltages.

The thyratron is a special-purpose tube filled with low-pressure gas or mercury vapor. Like vacuum tubes, it contains a hot cathode and an anode, but also a control electrode which behaves somewhat like the grid of a triode.

When the control electrode starts conduction, the gas ionizes, after which the control electrode can no longer stop the current; the tube "latches" into conduction.

Removing anode plate voltage lets the gas de-ionize, restoring its non-conductive state. Some thyratrons can carry large currents for their physical size.

One example is the miniature type 2D21, often seen in s jukeboxes as control switches for relays. A cold-cathode version of the thyratron, which uses a pool of mercury for its cathode, is called an ignitron ; some can switch thousands of amperes.

Thyratrons containing hydrogen have a very consistent time delay between their turn-on pulse and full conduction; they behave much like modern silicon-controlled rectifiers , also called thyristors due to their functional similarity to thyratrons.

Hydrogen thyratrons have long been used in radar transmitters. A specialized tube is the krytron , which is used for rapid high-voltage switching.

Krytrons are used to initiate the detonations used to set off a nuclear weapon ; krytrons are heavily controlled at an international level. X-ray tubes are used in medical imaging among other uses.

X-ray tubes used for continuous-duty operation in fluoroscopy and CT imaging equipment may use a focused cathode and a rotating anode to dissipate the large amounts of heat thereby generated.

These are housed in an oil-filled aluminum housing to provide cooling. The photomultiplier tube is an extremely sensitive detector of light, which uses the photoelectric effect and secondary emission , rather than thermionic emission, to generate and amplify electrical signals.

Nuclear medicine imaging equipment and liquid scintillation counters use photomultiplier tube arrays to detect low-intensity scintillation due to ionizing radiation.

The Ignatron tube was used in resistance welding equipment in the early s. The Ignatron had a cathode, anode and an igniter. The tube base was filled with mercury and the tube was used as a very high current switch.

A large current potential was placed between the anode and cathode of the tube but was only permitted to conduct when the igniter in contact with the mercury had enough current to vaporize the mercury and complete the circuit.

Because this was used in resistance welding there were two Ignatrons for the two phases of an AC circuit. Because of the mercury at the bottom of the tube they were extremely difficult to ship.

Batteries provided the voltages required by tubes in early radio sets. Three different voltages were generally required, using three different batteries designated as the A , B , and C battery.

The "A" battery or LT low-tension battery provided the filament voltage. Tube heaters were designed for single, double or triple-cell lead-acid batteries, giving nominal heater voltages of 2 V, 4 V or 6 V.

In portable radios, dry batteries were sometimes used with 1. Reducing filament consumption improved the life span of batteries.

By towards the end of the tube era, tubes using only 50 mA down to as little as 10 mA for the heaters had been developed.

The high voltage applied to the anode plate was provided by the "B" battery or the HT high-tension supply or battery. These were generally of dry cell construction and typically came in Early sets used a grid bias battery or "C" battery which was connected to provide a negative voltage.

Since no current flows through a tube's grid connection, these batteries had no current drain and lasted the longest, usually limited by their own shelf life.

The supply from the grid bias battery was rarely, if ever, disconnected when the radio was otherwise switched off. Even after AC power supplies became commonplace, some radio sets continued to be built with C batteries, as they would almost never need replacing.

The "C battery" for bias is a designation having no relation to the " C cell " battery size. Battery replacement was a major operating cost for early radio receiver users.

The development of the battery eliminator , and, in , batteryless receivers operated by household power , reduced operating costs and contributed to the growing popularity of radio.

A power supply using a transformer with several windings, one or more rectifiers which may themselves be vacuum tubes , and large filter capacitors provided the required direct current voltages from the alternating current source.

As a cost reduction measure, especially in high-volume consumer receivers, all the tube heaters could be connected in series across the AC supply using heaters requiring the same current and with a similar warm-up time.

In one such design, a tap on the tube heater string supplied the 6 volts needed for the dial light. By deriving the high voltage from a half-wave rectifier directly connected to the AC mains, the heavy and costly power transformer was eliminated.

Where the mains voltage was in the — V range, this limited voltage proved suitable only for low-power receivers. Television receivers either required a transformer or could use a voltage doubling circuit.

Where V nominal mains voltage was used, television receivers as well could dispense with a power transformer. Transformer-less power supplies required safety precautions in their design to limit the shock hazard to users, such as electrically insulated cabinets and an interlock tying the power cord to the cabinet back, so the line cord was necessarily disconnected if the user or service person opened the cabinet.

A cheater cord was a power cord ending in the special socket used by the safety interlock; servicers could then power the device with the hazardous voltages exposed.

To avoid the warm-up delay, "instant on" television receivers passed a small heating current through their tubes even when the set was nominally off.

At switch on, full heating current was provided and the set would play almost immediately. One reliability problem of tubes with oxide cathodes is the possibility that the cathode may slowly become " poisoned " by gas molecules from other elements in the tube, which reduce its ability to emit electrons.

Trapped gases or slow gas leaks can also damage the cathode or cause plate anode current runaway due to ionization of free gas molecules.

Vacuum hardness and proper selection of construction materials are the major influences on tube lifetime. Depending on the material, temperature and construction, the surface material of the cathode may also diffuse onto other elements.

The resistive heaters that heat the cathodes may break in a manner similar to incandescent lamp filaments, but rarely do, since they operate at much lower temperatures than lamps.

The heater's failure mode is typically a stress-related fracture of the tungsten wire or at a weld point and generally occurs after accruing many thermal power on-off cycles.

Tungsten wire has a very low resistance when at room temperature. A negative temperature coefficient device, such as a thermistor , may be incorporated in the equipment's heater supply or a ramp-up circuit may be employed to allow the heater or filaments to reach operating temperature more gradually than if powered-up in a step-function.

Low-cost radios had tubes with heaters connected in series, with a total voltage equal to that of the line mains. Some receivers made before World War II had series-string heaters with total voltage less than that of the mains.

Some had a resistance wire running the length of the power cord to drop the voltage to the tubes. Others had series resistors made like regular tubes; they were called ballast tubes.

Following World War II, tubes intended to be used in series heater strings were redesigned to all have the same "controlled" warm-up time.

Earlier designs had quite-different thermal time constants. The audio output stage, for instance, had a larger cathode and warmed up more slowly than lower-powered tubes.

The result was that heaters that warmed up faster also temporarily had higher resistance, because of their positive temperature coefficient.

This disproportionate resistance caused them to temporarily operate with heater voltages well above their ratings, and shortened their life.

Another important reliability problem is caused by air leakage into the tube. Usually oxygen in the air reacts chemically with the hot filament or cathode, quickly ruining it.

Designers developed tube designs that sealed reliably. This was why most tubes were constructed of glass. Metal alloys such as Cunife and Fernico and glasses had been developed for light bulbs that expanded and contracted in similar amounts, as temperature changed.

These made it easy to construct an insulating envelope of glass, while passing connection wires through the glass to the electrodes.

When a vacuum tube is overloaded or operated past its design dissipation, its anode plate may glow red. In consumer equipment, a glowing plate is universally a sign of an overloaded tube.

However, some large transmitting tubes are designed to operate with their anodes at red, orange, or in rare cases, white heat. The only way to know the particular features of a special quality part is by reading the datasheet.

The valve was in service from until and had a recorded life of , hours. The BBC maintained meticulous records of their valves' lives with periodic returns to their central valve stores.

A vacuum tube needs an extremely good "hard" vacuum to avoid the consequences of generating positive ions within the tube.

With a small amount of residual gas, some of those atoms may ionize when struck by an electron and create fields that adversely affect the tube characteristics.

Larger amounts of residual gas can create a self-sustaining visible glow discharge between the tube elements. Commercial vacuum tubes are evacuated at manufacture to about 0.

To prevent gases from compromising the tube's vacuum, modern tubes are constructed with " getters ", which are usually small, circular troughs filled with metals that oxidize quickly, barium being the most common.

While the tube envelope is being evacuated, the internal parts except the getter are heated by RF induction heating to evolve any remaining gas from the metal parts.

The tube is then sealed and the getter is heated to a high temperature, again by radio frequency induction heating, which causes the getter material to vaporize and react with any residual gas.

The vapor is deposited on the inside of the glass envelope, leaving a silver-colored metallic patch that continues to absorb small amounts of gas that may leak into the tube during its working life.

Great care is taken with the valve design to ensure this material is not deposited on any of the working electrodes. If a tube develops a serious leak in the envelope, this deposit turns a white color as it reacts with atmospheric oxygen.

Large transmitting and specialized tubes often use more exotic getter materials, such as zirconium. Early gettered tubes used phosphorus-based getters, and these tubes are easily identifiable, as the phosphorus leaves a characteristic orange or rainbow deposit on the glass.

The use of phosphorus was short-lived and was quickly replaced by the superior barium getters. Unlike the barium getters, the phosphorus did not absorb any further gases once it had fired.

Getters act by chemically combining with residual or infiltrating gases, but are unable to counteract non-reactive inert gases. A known problem, mostly affecting valves with large envelopes such as cathode ray tubes and camera tubes such as iconoscopes , orthicons , and image orthicons , comes from helium infiltration.

This effect cannot be rectified short of re-evacuation and resealing , and is responsible for working examples of such tubes becoming rarer and rarer.

Unused "New Old Stock" tubes can also exhibit inert gas infiltration, so there is no long-term guarantee of these tube types surviving into the future.

An extremely thin molecular layer of thorium atoms forms on the outside of the wire's carbonized layer and, when heated, serve as an efficient source of electrons.

The thorium slowly evaporates from the wire surface, while new thorium atoms diffuse to the surface to replace them. Such thoriated tungsten cathodes usually deliver lifetimes in the tens of thousands of hours.

The end-of-life scenario for a thoriated-tungsten filament is when the carbonized layer has mostly been converted back into another form of tungsten carbide and emission begins to drop off rapidly; a complete loss of thorium has never been found to be a factor in the end-of-life in a tube with this type of emitter.

While it was commonly believed that at RF power levels above approximately 20 kilowatts, vacuum tubes were more efficient than solid-state circuits, this is no longer the case, especially in medium wave AM broadcast service where solid-state transmitters at nearly all power levels have measurably higher efficiency.

Cathodes in small "receiving" tubes are coated with a mixture of barium oxide and strontium oxide , sometimes with addition of calcium oxide or aluminium oxide.

An electric heater is inserted into the cathode sleeve and insulated from it electrically by a coating of aluminum oxide. This complex construction causes barium and strontium atoms to diffuse to the surface of the cathode and emit electrons when heated to about degrees Celsius.

A catastrophic failure is one that suddenly makes the vacuum tube unusable. A crack in the glass envelope will allow air into the tube and destroy it.

Cracks may result from stress in the glass, bent pins or impacts; tube sockets must allow for thermal expansion, to prevent stress in the glass at the pins.

Stress may accumulate if a metal shield or other object presses on the tube envelope and causes differential heating of the glass.

Glass may also be damaged by high-voltage arcing. Tube heaters may also fail without warning, especially if exposed to over voltage or as a result of manufacturing defects.

Tube heaters do not normally fail by evaporation like lamp filaments since they operate at much lower temperature. The surge of inrush current when the heater is first energized causes stress in the heater and can be avoided by slowly warming the heaters, gradually increasing current with a NTC thermistor included in the circuit.

Tubes intended for series-string operation of the heaters across the supply have a specified controlled warm-up time to avoid excess voltage on some heaters as others warm up.

Directly heated filament-type cathodes as used in battery-operated tubes or some rectifiers may fail if the filament sags, causing internal arcing.

Excess heater-to-cathode voltage in indirectly heated cathodes can break down the insulation between elements and destroy the heater.

Arcing between tube elements can destroy the tube. An arc can be caused by applying voltage to the anode plate before the cathode has come up to operating temperature, or by drawing excess current through a rectifier, which damages the emission coating.

Arcs can also be initiated by any loose material inside the tube, or by excess screen voltage. An arc inside the tube allows gas to evolve from the tube materials, and may deposit conductive material on internal insulating spacers.

Tube rectifiers have limited current capability and exceeding ratings will eventually destroy a tube. Overheating of internal parts, such as control grids or mica spacer insulators, can result in trapped gas escaping into the tube; this can reduce performance.

A getter is used to absorb gases evolved during tube operation but has only a limited ability to combine with gas. Control of the envelope temperature prevents some types of gassing.

A tube with an unusually high level of internal gas may exhibit a visible blue glow when plate voltage is applied.

The getter being a highly reactive metal is effective against many atmospheric gases but has no or very limited chemical reactivity to inert gases such as helium.

One progressive type of failure, especially with physically large envelopes such as those used by camera tubes and cathode-ray tubes, comes from helium infiltration.

The exact mechanism is not clear: the metal-to-glass lead-in seals are one possible infiltration site. Gas and ions within the tube contribute to grid current which can disturb operation of a vacuum tube circuit.

Another effect of overheating is the slow deposit of metallic vapors on internal spacers, resulting in inter-element leakage.

Tubes on standby for long periods, with heater voltage applied, may develop high cathode interface resistance and display poor emission characteristics.

This effect occurred especially in pulse and digital circuits , where tubes had no plate current flowing for extended times. Tubes designed specifically for this mode of operation were made.

Cathode depletion is the loss of emission after thousands of hours of normal use. Sometimes emission can be restored for a time by raising heater voltage, either for a short time or a permanent increase of a few percent.

Cathode depletion was uncommon in signal tubes but was a frequent cause of failure of monochrome television cathode-ray tubes.

Vacuum tubes may develop defects in operation that make an individual tube unsuitable in a given device, although it may perform satisfactorily in another application.

Microphonics refers to internal vibrations of tube elements which modulate the tube's signal in an undesirable way; sound or vibration pick-up may affect the signals, or even cause uncontrolled howling if a feedback path with greater than unity gain develops between a microphonic tube and, for example, a loudspeaker.

Leakage current between AC heaters and the cathode may couple into the circuit, or electrons emitted directly from the ends of the heater may also inject hum into the signal.

Leakage current due to internal contamination may also inject noise. Selecting the best of a batch of nominally identical tubes for critical applications can produce better results.

Tube pins can develop non-conducting or high resistance surface films due to heat or dirt. Pins can be cleaned to restore conductance.

Most small signal vacuum tube devices have been superseded by semiconductors, but some vacuum tube electronic devices are still in common use.

The magnetron is the type of tube used in all microwave ovens. In spite of the advancing state of the art in power semiconductor technology, the vacuum tube still has reliability and cost advantages for high-frequency RF power generation.

Some tubes, such as magnetrons , traveling-wave tubes , carcinotrons , and klystrons , combine magnetic and electrostatic effects.

These are efficient usually narrow-band RF generators and still find use in radar , microwave ovens and industrial heating.
