Ideal Vacuum Cube 6 x 12 TVAC Thermal Vacuum Chamber Heater Plate for up to 140 Degrees C. This Ideal Vacuum Cube 6 x 12 inch heater plate will safely provide up to 140°C of uniformly distributed heat to the vacuum side of the plate surface, through a 120VAC 360W heating element. This thermal vacuum plate expands the capabilities of the Ideal Vacuum Cube whereby the Cube can be used as a Thermal Vacuum Chamber (TVAC). Applications include thermal stability testing, surface coating and implantation, and damage testing under thermal load. Thermal Vacuum Chambers are often used to replicate or simulate the extreme conditions of outer space and are frequently employed in the testing of spacecraft and aerospace parts or components under a simulated space environment, and control outgassing for a giving process. Please note that the maximum allowable temperature using Viton O-rings is 150°C. This heater plate has an integrated Type-K thermocouple, and works directly with our single zone PID Plug & Play Heater Control System, which is designed to accurately measure and control the temperature of our Cube heater plates. When a single Cube heater plate is used, and once the system has reached thermal equilibrium, the rest of the chamber will be approximately 10°C less than the heated plate itself. Multiple heater plates may be used (up to the heater control system’s maximum power load) to help eliminate this temperature differential. These Vacuum Cube heater plates are machined from 6061-T6 aluminum and powder coated red. The vacuum chamber side (back) of these heater plates have an optical breadboard for fixtures and test components. Temperature gradients due to conductive losses through the heater plate edges are kept to a minimum with integrated, machined stand-offs that minimize the contact surface between the plate and the Vacuum Cube frame. An aluminum anodized shield on the air side of the heater plate helps control convective losses due to ambient conditions (and helps protect users from direct contact with the heated plate). As the plots below demonstrate, ramp-up time and maximum plate temperature is dependent upon the heater control system, number of heater plates, ambient operating conditions, and whether the vacuum cube is insulated. Features: 6 x 12 plate 6061-T6 aluminum Red powdercoat Heats to 140°C, 120VAC, 360W Anodized shield helps control convective losses and protect users from direct heater contact Internal optical breadboard Mounts in any orientation Works with PID heater control system P107361 Directly mounts to frame size: 6x6x12 6x12x12 6x6x12 hexagon 6x6x12 octagon This plate can also be mounted on any 12 x 12 x 12, or 24 x 24 x 24 frame with a plate adapter kit.

Ideal Vacuum Cube, 6 x 12 inch Non-Thermally Isolated Chamber Plate For Circulating Hot or Cold Fluids. This is a non-thermally isolated Ideal Vacuum Cube 6 x 12 inch TVAC plate with 3/8” OD fluid tubes. This plate allows the vacuum side of the plate to be thermally controlled by circulating hot or cold fluids through its stainless steel tubes and internal cavity. The operating range of this plate is 150°C to -26°C (302°F to -15°F). This thermal vacuum Cube plate allows the Ideal Vacuum Cube to be used as a thermal vacuum or thermal shock vacuum chamber. It can also function as a chilled trap for chemical and high boiling point liquids. Multiple TVAC plates may be mounted to a Cube and plumbed together to enhance temperature control capability. Fluid is commonly supplied by a recirculating heater or chiller such as those made by Thermo Scientific, Neslab, and Huber. Insulated supply and return hoses connect the heater/chiller system to the thermal plate with 3/8" OD tube fittings. The plate’s core is made of 304L stainless steel and has an optical breadboard on the vacuum side with a 10.275" x 3.0" temperature-controlled area. Because the thermal cavity is not thermally isolated from the rest of the plate, operating temperatures are limited to that of the plate’s Viton O-ring vacuum seal. The plate is designed to occupy minimal volume within the Cube envelope and may be mounted in any orientation. Features: 6" x 12" plate 6061-T6 aluminum Blue powdercoat 3/8” OD stainless steel supply and return tubes Operating temperature range 150°C to -26°C (302°F to -15°F) 10.275" x 3.0" temperature-controlled core Internal optical breadboard Mounts in any orientation Directly mounts to frame size: 6x6x12 6x12x12 6x6x12 hexagon 6x6x12 octagon This plate can also be mounted on any 12 x 12 x 12, or 24 x 24 x 24 frame with a plate adapter kit.

Ideal Vacuum Cube Viewing Window Plate Assembly for 6x12 Vacuum Chamber 3/8" Tempered Glass. This Ideal Vacuum Cube 6x12 inch vacuum chamber standard, low-iron, tempered glass viewing window plate assembly is designed to fit our 6x6x12 or 6x12x12 modular Cube chambers. The standard tempered glass window viewing plate assembly is a popular Cube option, commonly used for general, direct observation of roughing or high-vacuum chamber processes and can be used to facilitate optical alignments of chamber components, observe degassing of fluids, or used to help teach in-vacuo processes by direct observation. The glass material is 3/8" thick, tempered, low-iron, high-clarity glass. Surface quality and flatness is Q4 per ASTM 1036-06 and 1048-04. The low iron content of the glass results in it having a slight blueish tint. This economical glass is unsuitable for high power laser experiments. We also offer high purity fused silica windows which are ground and polished to optical grade on both sides with a total thickness variation (TTV) of <10µm, a surface finish of S/D 40/20, and a surface roughness of Ra < 1 nm. These windows have appreciably improved transmittance, and a wider useful wavelength range than standard glass. Characteristics include extraordinarily low refractive index variations, low birefringence values, and an ultra-low thermal expansion coefficient. Fused silica is used for transmissive optics where a high laser damage threshold is required. Fused silica is used for optics operating in the deep UV, visible, and the near infrared wavelength range. Our Cube viewing windows employ an innovative, zero metal-to-glass contact design that holds the 3/8” thick window pane to an aluminum mounting plate. This cushioned window mounting system ensures operator safety and is less prone to leakage than other viewport window configurations, even at high vacuum pressures. Ideal Vacuum Cube windows are delivered fully assembled and use Viton O-rings and Teflon spacers. Bakeout temperatures to 150 °C are permissible. The viewing window plate assembly is interchangeable with other Cube plates and can be added to an Ideal Vacuum Cube system anytime. The viewing window can be implemented as a fixed side, or a door (with our optional hinge assembly and hardware kit, P106868) on the Cube chamber. The viewing window plate assembly, like all our other Cube plates, is built with our patented Taper-Seal technology which incorporates sloped sealing features to help prevent damage to the vacuum sealing surfaces. All Ideal Vacuum Cube plates are CNC milled from a single block of lightweight 6061-T6 Aluminum Alloy. Before it ships, every viewing window plate assembly is visually inspected for window media imperfections, helium leak tested, cleaned and sealed, ensuring that it operates correctly, safely, and is ready for immediate installation upon delivery. NOTE: All viewing windows or viewports are inherently fragile, should be handled carefully, and always inspected before use. Ideal Vacuum viewing windows are designed and rated for VACUUM ONLY and can be susceptible to thermal shock if exposed to rapid temperature changes (>10° C /min). If directing a laser beam through the window, make sure the laser’s wavelength can be reasonably transmitted through the window’s material. Please download and read all the safety warnings in the IVP Cube Viewing Window Assembly Manual. Ideal Vacuum Cube IntroductionOur Ideal Vacuum Cube is a modular high-vacuum chamber system, conceived to enable creativity and design flexibility in vacuum chamber system construction. Cubes can be stacked together into various shapes and configurations, with interchangeable plates offering a variety of features for connections, windows, and feedthroughs. Plates include 1/4"-20 mounting threads on a standard 1" optical pattern for easy connection of hinges, posts, mounts, lenses, polarizers, and other accessories. Durability and VersatilityThe large inner dimensions and open design of Ideal Vacuum Cubes makes them perfect for many vacuum chamber applications and experiments. Vacuum Cubes are constructed of lightweight 6061-T6 aluminum alloy, allowing them to be easily transported around the lab and mounted on optical tables (unlike heavy stainless steel vacuum chambers). A patent-pending seal protective design, stainless steel thread inserts, and powder-coated outside plate finish help make the Vacuum Cube a durable tool for even the most demanding use. Technical DetailsPatented Chamber SystemOur Ideal Vacuum Cubes have a patented design which features our Taper-Seal technology. Unlike other vacuum flange designs, such as, Conflat CF, KF/NW, or ISO-LF (large flange), which can be easily damaged when set on work surfaces, our Taper-Seal design protects critical sealing edges and o-rings from contact which can cause damage or contamination. Innovative Chamber Building BlocksIdeal Vacuum Cubes can easily be stacked together to build a complex, yet lightweight vacuum system (see graphic below). The outer edges of each vacuum cube feature hardware mounting sockets for easy cube-to-cube connections. A cube coupling kit includes the hardware needed to connect two cubes together. This allows scientists to creatively construct long or odd-shaped vacuum systems in a laboratory. Configurable Plates and AccessoriesThe Vacuum Cube can be configured with a wide variety of plates and windows with many options. A Vacuum Cube can be fitted feedthroughs for electrical power, thermocouple temperature measurements, optical lasers light or imaging detectors, gas supply, or fluid flow for heat/cooling recirculation lines. Compatible standard flange styles include KF-16, KF-25, KF-40, KF-50, ISO-63, along with conlfat CF 2.75, CF 3.375, and CF 4.5 inch flanged ports. Viewing windows are also available, and custom plates can be manufactured on request. An optional hinge kit can be ordered to convert any plate into an operable door. Applications for Ideal Vacuum CubesOur Ideal Vacuum Cubes are designed to implement well into optics laboratories for quick installation in laser research applications. The graphic below depicts an example laser spectroscopy laboratory setup, cavity ring down spectroscopy (CRDS) vacuum chamber system, using a 6x6x18 inch Ideal Vacuum Cube chamber. The modular design of our Ideal Vacuum Cubes make them suitable for many vacuum chamber applications: Vacuum Ultraviolet (VUV) Devices and Experiments Thermal Vacuum Testing Altitude Testing Vacuum Degassing Chamber High Power and Ultra Short Pulsed Lasers Research and Development Ion Acceleration RGA (Residual Gas Analyzers) Helium Leak Testing of Hermetic Sealed Devices With Welded In Helium Atmosphere Leak Detection Of Pharma Packaging Spectroscopy Molecular Ion Trap Cryostat Vacuum Chamber Beamlines Vacuum Cube Pumping Performance The pump down curves for several Ideal Vacuum Cube configurations are shown in the graphs below. A single 6x6x6 inch Cube can be pumped from atmosphere to 1x10-5 Torr in 2.5 minutes and below 1x10-6 Torr in around 15 minutes. (view curves graphic 1) close image This was accomplished using a 68 liters/second turbomolecular pump backed by a 110 liters/minute (3.3 cfm) dry scroll vacuum pump. We have also provided roughing pump down curves for popular Agilent Varian IDP-3 and SH-110 dry scroll pumps. The 6x6x6 Cube reaches base pressure of 300 mTorr for the IDP-3 (2.1 cfm) in less than 1 minute of pumping, and 50 mTorr for Agilent Varian SH-110 (3.3 cfm) in around 2 minutes. (view curves graphic 2) close image On special request we can offer fully anodized plates to help with absorption of scattered light in laser research and optical applications. Anodized components do not pump down as fast as bare aluminum metal surfaces. (view curves graphic 3) close image A single 6x6x6 with anodized plates required 1 hour of pumping to reach 1x10-5 Torr.

The fused quartz window viewing plate assembly is often selected for experiments where improved optical clarity, extended wavelength transmissivity is required beyond the visible range, and where cost is a factor. Our fused quartz windows are manufactured with the highest quality natural quartz resulting in the highest levels of purity and lowest inclusion and bubble levels. Comparable to Heraeus TSC-3, these windows have improved transmittance, and a wider useful wavelength range than standard glass. Characteristics include low refractive index variations and low thermal expansion coefficient. Fused quartz is used for semiconductor applications such as plasma etch and deposition systems and recommended when low alkali and low aluminum content are specified. It is often used for transmissive optics in the visible and near-to-mid infrared wavelengths where a high laser damage threshold is required. Fused quartz has absorbtion bands in the 2600 to 2900 nm region, similar to fused silica but not as strong. It is unsuitable for UV work due to absorbtion in the 270 nm region. Note that fused quartz stock is limited as Ideal Vacuum is transitioning to fused silica as its premium window offering. Also note that fused quartz windows may be erroneously labeled with fused silica part numbers. You may verify your window material by checking your sales invoice. We also offer Cube window plate assemblies and replacement window panes with standard low-iron tempered glass or fused silica. Tempered glass is commonly used for general, direct observation of roughing or high-vacuum chamber processes and can be used to facilitate optical alignments of chamber components, observe degassing of fluids, or used to help teach in-vacuo processes by direct observation. The glass material is standard low-iron float glass. Surface quality and flatness is Q4 per ASTM 1036-06 and 1048-04. The low iron content of the glass results in it having a slight blueish tint. This economical glass is unsuitable for laser experiments below visible or beyond near-infrared (NIR) wavelengths. Our high purity fused silica replacement windows are ground and polished to optical grade on both sides with a total thickness variation (TTV) of <10µm, a surface finish of S/D 40/20, and a surface roughness of Ra < 1 nm. These windows have appreciably improved transmittance, and a wider useful wavelength range than standard glass. Characteristics include extraordinarily low refractive index variations, low birefringence values, and an ultra-low thermal expansion coefficient. Fused silica is used for transmissive optics where a high laser damage threshold is required. Fused silica is used for optics operating in the deep UV, visible, and the near infrared wavelength range. Our Cube viewing windows employ an innovative, zero metal-to-glass contact design that holds the 3/8” thick window pane to an aluminum mounting plate. This cushioned window mounting system ensures operator safety and is less prone to leakage than other viewport window configurations, even at high vacuum pressures. Ideal Vacuum Cube windows are delivered fully assembled and use Viton O-rings and Teflon spacers. Bakeout temperatures to 150 °C are permissible. The viewing window plate assembly is interchangeable with other Cube plates and can be added to an Ideal Vacuum Cube system anytime. The viewing window can be implemented as a fixed side, or a door (with our optional hinge assembly and hardware kit, P106868) on the Cube chamber. The viewing window plate assembly, like all our other Cube plates, is built with our patented Taper-Seal technology which incorporates sloped sealing features to help prevent damage to the vacuum sealing surfaces. All Ideal Vacuum Cube plates are CNC milled from a single block of lightweight 6061-T6 Aluminum Alloy. Before it ships, every viewing window plate assembly is visually inspected for window media imperfections, helium leak tested, cleaned and sealed, ensuring that it operates correctly, safely, and is ready for immediate installation upon delivery. NOTE: All viewing windows or viewports are inherently fragile, should be handled carefully, and always inspected before use. Ideal Vacuum viewing windows are designed and rated for VACUUM ONLY and can be susceptible to thermal shock if exposed to rapid temperature changes (>10° C /min). If directing a laser beam through the window, make sure the laser’s wavelength can be reasonably transmitted through the window’s material.

Ideal Vacuum Cube IntroductionOur Ideal Vacuum Cube is a modular high-vacuum chamber system, conceived to enable creativity and design flexibility in vacuum chamber system construction. Cubes can be stacked together into various shapes and configurations, with interchangeable plates offering a variety of features for connections, windows, and feedthroughs. Plates include 1/4"-20 mounting threads on a standard 1" optical pattern for easy connection of hinges, posts, mounts, lenses, polarizers, and other accessories. Durability and VersatilityThe large inner dimensions and open design of Ideal Vacuum Cubes makes them perfect for many vacuum chamber applications and experiments. Vacuum Cubes are constructed of lightweight 6061-T6 aluminum alloy, allowing them to be easily transported around the lab and mounted on optical tables (unlike heavy stainless steel vacuum chambers). A patent-pending seal protective design, stainless steel thread inserts, and powder-coated outside plate finish help make the Vacuum Cube a durable tool for even the most demanding use. Technical DetailsPatented Chamber SystemOur Ideal Vacuum Cubes have a patented design which features our Taper-Seal technology. Unlike other vacuum flange designs, such as, Conflat CF, KF/NW, or ISO-LF (large flange), which can be easily damaged when set on work surfaces, our Taper-Seal design protects critical sealing edges and o-rings from contact which can cause damage or contamination. Innovative Chamber Building BlocksIdeal Vacuum Cubes can easily be stacked together to build a complex, yet lightweight vacuum system (see graphic below). The outer edges of each vacuum cube feature hardware mounting sockets for easy cube-to-cube connections. A cube coupling kit includes the hardware needed to connect two cubes together. This allows scientists to creatively construct long or odd-shaped vacuum systems in a laboratory. Configurable Plates and AccessoriesThe Vacuum Cube can be configured with a wide variety of plates and windows with many options. A Vacuum Cube can be fitted feedthroughs for electrical power, thermocouple temperature measurements, optical lasers light or imaging detectors, gas supply, or fluid flow for heat/cooling recirculation lines. Compatible standard flange styles include KF-16, KF-25, KF-40, KF-50, ISO-63, along with conlfat CF 2.75, CF 3.375, and CF 4.5 inch flanged ports. Viewing windows are also available, and custom plates can be manufactured on request. An optional hinge kit can be ordered to convert any plate into an operable door. Applications for Ideal Vacuum CubesOur Ideal Vacuum Cubes are designed to implement well into optics laboratories for quick installation in laser research applications. The graphic below depicts an example laser spectroscopy laboratory setup, cavity ring down spectroscopy (CRDS) vacuum chamber system, using a 6x6x18 inch Ideal Vacuum Cube chamber. The modular design of our Ideal Vacuum Cubes make them suitable for many vacuum chamber applications: Vacuum Ultraviolet (VUV) Devices and Experiments Thermal Vacuum Testing Altitude Testing Vacuum Degassing Chamber High Power and Ultra Short Pulsed Lasers Research and Development Ion Acceleration RGA (Residual Gas Analyzers) Helium Leak Testing of Hermetic Sealed Devices With Welded In Helium Atmosphere Leak Detection Of Pharma Packaging Spectroscopy Molecular Ion Trap Cryostat Vacuum Chamber Beamlines Vacuum Cube Pumping Performance The pump down curves for several Ideal Vacuum Cube configurations are shown in the graphs below. A single 6x6x6 inch Cube can be pumped from atmosphere to 1x10-5 Torr in 2.5 minutes and below 1x10-6 Torr in around 15 minutes. (view curves graphic 1) close image This was accomplished using a 68 liters/second turbomolecular pump backed by a 110 liters/minute (3.3 cfm) dry scroll vacuum pump. We have also provided roughing pump down curves for popular Agilent Varian IDP-3 and SH-110 dry scroll pumps. The 6x6x6 Cube reaches base pressure of 300 mTorr for the IDP-3 (2.1 cfm) in less than 1 minute of pumping, and 50 mTorr for Agilent Varian SH-110 (3.3 cfm) in around 2 minutes. (view curves graphic 2) close image On special request we can offer fully anodized plates to help with absorption of scattered light in laser research and optical applications. Anodized components do not pump down as fast as bare aluminum metal surfaces. (view curves graphic 3) close image A single 6x6x6 with anodized plates required 1 hour of pumping to reach 1x10-5 Torr.
