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.
