Cylinder Acrylic Vacuum Chambers with Removable Top Lids

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.

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

Double-ended, 50-ohm connectors allow small electronics to operate within the chamber.

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).

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.

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.

Precision-routed channel ensures uniform seal along chamber perimeter to provide an ultra-low leak rate.

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