Biosafety Pass Box
Solves the material-transfer airtightness problem in high-containment laboratories — both doors seal mechanically to form an airtight band, with an interlock preventing cross-connection of areas at different contamination risk.
Overview
The Fenggu Biosafety Pass Box solves the material-transfer airtightness problem in high-containment laboratories (BSL-2/3, ABSL-3/4). Both doors seal mechanically — high-elasticity gaskets are compressed against the frame to form an airtight band, similar in principle to a mechanical gastight door — while a door interlock prevents direct connection between areas of different contamination risk.
A gas-disinfection port lets a VHP or other gas sterilizer decontaminate the chamber and its contents, with the effect open to validation. All product-contact surfaces are high-quality stainless steel resistant to disinfectants, detergents, acids and alkalis, and the fully sealed electrical interlock box can be serviced online.
Key Features
- Mechanical dual-door sealing — high-elasticity gaskets compressed to an airtight band
- Door interlock prevents connection between areas of different contamination risk
- Gas-disinfection port for VHP or other gas-sterilizer decontamination (validatable)
- Stainless product-contact surfaces resistant to disinfectants, detergents, acids and alkalis
- Fully sealed electrical interlock box, serviceable online
- Optional ISO 5 self-cleaning with circulation fan running
