Optional 25-pin connector can be used to monitor conditions within the vacuum chamber.
Coaxial SMA Feedthrough
Double-ended, 50-ohm connectors allow small electronics to operate within the chamber.
Optional Vacuum Relief Valve
Adjustable pressure relief valve limits vacuum levels within the chamber, allowing pressure to be maintained at user-configured point. (NOTE: Vacuum pump must remain in operation to maintain desired vacuum level).
Precision Vacuum Gauge and Needle Valves
Vacuum chambers can be customized to include precision needle valves for exact application, monitoring, backfill, and bleeding of vacuum pressure in increments of ~1" Hg (~3% vacuum). The hardware is mounted over an extra layer of acrylic to prevent damage to the lid while the chamber is under maximum vacuum.
Inlaid O-Ring
Precision-routed channel ensures uniform seal along chamber perimeter to provide an ultra-low leak rate.
Tested to Hold Full Vacuum for 72 hours
Terra's acrylic vacuum chambers are tested to hold 29.9"Hg (99.9% vacuum) with no detectable change over a 72 hour duration. Heavy-duty one-inch-thick walls ensure chamber integrity and protect against cracking.
Electric height adjusting tables help easily position extremely heavy vacuum chambers to the right height to allow transfer of materials, or observe tests within the chamber.
Glass Top Lid for Vacuum Chamber
Glass Top Lid for vacuum chamber enhances precision and visibility for component testing within the vacuum chamber.

Terra’s Nitrogen Generators provide a continuous, reliable supply of clean, dry nitrogen up to 99% pure to eliminate dependence on bulky canisters to operate desiccators and glove boxes.
Ionizing Gun: LED Power Indicator
LED indicates when the Cleanroom Ionizing Blow-Off Gun is discharging ions and emitting clean air or nitrogen; low-voltage power source is intrinscially safe and meets static decay requirements
Small Nitrogen Generator for Single Glovebox or Desiccator Cabinet
Compact membrane nitrogen generator allows set-up wherever there's a compressed air supply. This small configuration provides output suitable for a single laboratory glovebox or 3-4 chamber desiccator.
Compact Nitrogen Generator, Large Size for Multiple Large Desiccator Cabinets or Gloveboxes
Compact nitrogen generator produces 99.5% pure N2 gas on demand, eliminating the need for costly nitrogen tanks. This large size N2 generator provides output suitable for six 10-chamber desiccators or six 4-port gloveboxes.
The eVAC Digital Vacuum Controller provides highly flexible control over vacuum levels by incorporating an electronically activated bleed valve, which adds the capability to reduce the applied vacuum.
Liquid/Gas Feed-Through
Liquid/Gas Feed-throughs are constructed to easily allow the passage of fluids into a vacuum environment for open or closed loop systems. These feed-throughs offer an additional tube section which acts as an extended thermal path, reducing ice build up or condensation that can occur on the side of the flange.
Electrical Power Feed-Through
Electrical power feed-throughs come in a wide variety of terminations, maximum voltages, and current carrying capacities. Weldable, CF and KF flanged, and baseplated mounted versions are available.
Thermocouple Feed-Through
Thermocouple feed-throughs are designed to transfer signals through the vacuum wall via multiple thermocouple material pairs. Weldable, CF and KF flanged, baseplate and NPT mounted versions are available.
Vacuum Chamber Viewports
A comprehensive range of viewports with various optic materials and surface treatments to allow for optimal transmission of specified wavelengths. These viewports offer a hermetically-sealed lens with different upgrades and applications.
