Features and Benefits

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.

Optional Glass Top for Sensitive Optics

0.75"-thick tempered-glass top allows optical testing and monitoring that requires high clarity.

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.
