Terra offers a wide selection of high-quality vacuum chambers for every application.Watch Terra's Vacuum Chamber VideoTerra 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.
Vacuum chambers provide a safe, reliable means for transporting contamination and moisture sensitive parts | 5235-08 displayedAcrylic Vacuum ChamberAcrylic Vacuum Chamber support full vacuum; select optional burst valve to limit vacuum pressure.
Features and Benefits
Electrode Feedthrough
Optional cord/cable feed-throughs for power cords, sensor cables, data lines and thermocouple connectors.
Installed Vacuum Gauge and Metering Valves
Gauges and valves preinstalled on vacuum chambers allow vacuum application, monitoring, bleeding and backfilling (shown mounted on aluminum chamber).
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).
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.
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.
Optional Glass Top for Sensitive Optics
0.75"-thick tempered-glass top allows optical testing and monitoring that requires high clarity.
Powder-Coated Aluminum Vacuum Chamber Walls
One-inch-thick, powder-coated aluminum walls ensure chamber cleanliness and integrity while subject to vacuum up to 29.9”Hg.
Powder-Coated Aluminum Vacuum Chamber Gauge and Metering Valves Inlaid O-Ring
O-ring rests in a precision-routed channel for an optimal seal that prevents leakage.
Viewing Window for Vacuum Chamber
A sealed, 1”-thick acrylic window affords a view of the chamber’s contents. Optional tempered glass viewing window for optical testing.
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.
