Terra offers a wide selection of high-quality vacuum chambers for every application. Watch Terra's Vacuum Chamber Video Terra offers a wide selection of high-quality vacuum chambers for every application. Economical, high-visibility acrylic vacuum chambers are ideal for most manufacturing, testing, and research applications. Terra's 1" thick welded acrylic (plexiglass) vacuum chambers hold a full vacuum (29.9"Hg) for 72 hours with no detectable leaks. Powder-coated aluminum vacuum chambers offer better chemical resistance than acrylic chambers, particularly when using disinfectants, such as isopropyl alcohol, or sporicidal agents. Stainless steel vacuum chambers are more suitable for chemical, biopharmaceutical, and microelectronics applications with higher temperatures and/or corrosive chemicals.

Features and Benefits

Vacuum Chamber Pre-Cycle

For optimal vacuum chamber performance, a pre-cycle must be performed to remove trace moisture clinging to the internal acrylic surfaces. Run the pre-cycle until vacuum pressures stabilize at 29.9" Hg, then begin standard operation.

Multi-pin Feedthrough

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.

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.

Inlaid Rubber O-Ring for Uniform Seal

Precision-routed channel and inlaid rubber O-ring ensures a uniform seal around the lid of your vacuum chamber. The O-ring is also removable in case it needs to be replaced.
