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.

Continuous Product Improvement

At Terra, we strive to develop and produce the highest quality products for our customers to improve health, safety, performance, and yields. Our product quality is enabled by high-grade manufacturing equipment and processes, 45 years of engineering and application expertise, and our commitment to continuously improve.

Vacuum Chamber on Electric Height Adjusting Table

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.

Products Compliant With Your ISO Rating

Provide Terra with your desired ISO rating. We will tailor the product to meet your rating and supply a certificate of compliance appended to your invoice, to be included in your compliance package. All certificates are archived in Terra's system for quick retrieval.

Glass Top Lid for Vacuum Chamber

Glass Top Lid for vacuum chamber enhances precision and visibility for component testing within the vacuum chamber.
