Terra's Aluminum Vacuum Chambers provide an optimal environment for vacuum testing and processing to one atmosphere (29.9" Hg), in a range of convenient chamber sizes.

The aluminum walls provide the strength necessary for sustained vacuum service without warping, which can lead to vacuum leaks. Both benchtop models (5235 series) and larger chambers (1590 series) feature 1"-thick walls. Optional castered powder-coated steel stands allow convenient transport of the larger chambers and vacuum pump. All chambers include two preinstalled metering valves and a 0 – 30" Hg vacuum gauge.

  FEATURES & BENEFITS | Aluminum Vacuum Chambers
Alt Text
1”-Thick Aluminum Walls
Solid aluminum walls ensure chamber integrity while subject to vacuum up to 29.9”Hg
Gauge and Metering Valves
Preinstalled gauges and valves allow for careful application and bleeding of vacuum pressure
Inlaid O-Ring
O-ring rests in a precision-routed channel for an optimal seal that prevents leakage

Viewing Window
A sealed, 1”-thick acrylic window affords a view of the chamber’s contents

Multi-pin Feed-Through
Optional 25-pin connector can be used to monitor conditions within the vacuum chamber.

Coaxial SMA Feed-Through
Double-ended, 50-ohm connectors allow small electronics to operate within the chamber

Electrode Feed-Through
Vacuum-sealed wire pass-throughs can be added to feed electrodes into the chamber for transmitting signals

Optional Burst Valve
Adjustable bleed valve that limits the vacuum levels within the chamber, preventing damage to contents

Nitrogen generator Nitrogen Generators give you a reliable point-of-use supply of up to 99%-pure nitrogen. Eliminate the drawbacks of canisters and 3rd-party suppliers! You control volume, purity and rate; all you need is a clean compressed-air feed. Terra's three sizes of maintenance-free membrane generators meet several capacity requirements are ideal for back-filling or continuous flow into desiccators, glove boxes, vacuum chambers and incubators.

Aluminum vs. Plastic
Terra offers chambers in both materials. Which is right for your application?

Acrylic Chambers
Economy: Lower material cost translates into a less expensive chamber.
Full visibility: You can add windows to an aluminum chamber, but nothing beats the 360-degree visibility offered by acrylic.

Aluminum Chambers
Chemical resistance: Aluminum stands up to Spor-Klenz®, alcohol and other sterilants, making it preferable in many bio/pharmaceutical applications. In addition, because many joining and sealing compounds are designed for use with metals, they may degrade acrylic and result in leaks or chamber failure.

Greater machining versatility: Aluminum allows easier addition of feed-throughs to accommodate power and data cords, electrodes and other accessories. These add-ons are more feasible on aluminum than acrylic chambers, which are more prone to cracks that develop into leaks over time. For such applications, an aluminum chamber is a wiser long-term processing solution.

More effective moisture barrier: Acrylic, because it is hygroscopic, allows moisture penetration on a molecular level. Under vacuum, these water molecules are released from the surface and may require several vacuum cycles to remove. These issues don’t occur with aluminum and other metallic moisture barriers.

Greater dimensional versatility: Due to greater strength, aluminum is more appropriate than acrylic for larger chamber sizes.
