clamping mechanism rather than compressed air, making it dependable in high-level animal and microbiology containment where power- or air-supply independence is valued. Radiused door corners and an embedded high-density EPDM gasket, compressed against the frame when the door closes, produce a tested minute-leak rate of just 0.024%. The door withstands &minus;2500 Pa without deformation and survives repeated high- and low-temperature storage, and the corrosion-resistant stainless construction tolerates formaldehyde, VHP and chlorine-dioxide fumigation. It suits any laboratory or cleanroom between BSL-2 and BSL-4.<\/p>\n<h2 style=\"margin-top:44px\">Key Features<\/h2>\n<ul class=\"fg-tlist\">\n<li>Mechanical clamping seal \u2014 no compressed-air supply required, dependable during power loss<\/li>\n<li>Tested 0.024% minute-leak rate (chamber to &minus;1095 Pa, decaying to &minus;974 Pa over 20 min)<\/li>\n<li>Withstands &minus;2500 Pa held for 10 minutes with no deformation<\/li>\n<li>High-density EPDM gasket resistant to formaldehyde, VHP and chlorine-dioxide fumigation<\/li>\n<li>Endures 12 h at 70 &deg;C and &minus;55 &deg;C, returning to normal operation after recovery<\/li>\n<li>Corrosion-resistant stainless construction;
