Biosafety Double-Door Autoclave
A pass-through biocontainment steam autoclave built around a jacketed 316L square chamber, opposing automatic vertical-sliding doors, a continuous building bioseal, separate controls at both ends, filtered air removal and a closed condensate-retention path.
- Opposing Vertical-Sliding Doors
- Jacketed 316L Square Chamber
- Continuous Building Bioseal
- Filtered Exhaust and Closed Effluent Path
Product Introduction
The Biosafety Double-Door Autoclave is a through-wall steam-processing barrier for compatible laboratory loads moving out of a controlled containment zone. Its rectangular 316L pressure chamber is surrounded by a sectional jacket and terminates in automatic vertical-sliding doors at opposite ends, rather than two doors on one face. A continuous external bioseal closes the interface between the sterilizer body and the building opening, while separate compression gaskets seal the two pressure doors. Each end has its own HMI and door-status controls; the interlock prevents both doors from opening together and retains the receiving-side door until the configured cycle-release conditions are satisfied. Removed air passes through a dedicated HEPA housing, and chamber condensate enters a closed effluent-retention module instead of an open drain bottle. The illustrated floor-mounted arrangement uses four adjustable leveling feet plus an organized service-side run of stainless piping, isolation valves and blue manual handles. Chamber size, process recipe, exhaust-filter treatment, effluent hold logic and release criteria must be selected and verified for the actual load and facility risk assessment.
Key Features
The external bioseal flange and elastomeric wall gasket maintain the building barrier independently of the two pressure-door seals around the chamber openings.
A dedicated HEPA-filtered air-removal path and closed condensate-retention module keep exhaust and liquid effluent within configured treatment routes before release.
Separate near-side and far-side controls display cycle and door status at both ends, avoiding routine operator travel through the room boundary to operate the opposite face.
Customer Product Concerns
A biosafety pass-through autoclave must protect the room barrier not only at its doors, but also along the wall interface, filtered air-removal route and condensate discharge path.
Doors placed on the same face, or two opposing doors that can open together, would create an uncontrolled shortcut across the containment boundary.The selected chamber has one vertical-sliding door at each opposite end, with a one-door-at-a-time interlock and receiving-side release logic tied to configured cycle conditions.
Air removed from porous waste or sealed laboratory loads can carry aerosols into an unprotected service exhaust line.The air-removal route passes through a dedicated service-side HEPA housing that can be configured for in-situ treatment and integrity-test access.
Chamber condensate sent directly to an open drain or bottle can bypass the intended biocontainment process boundary.A closed stainless effluent module retains and conditions condensate within an isolated valve path until the configured discharge criteria are met.
A single control station forces staff to cross zones or rely on verbal confirmation before loading and unloading.Independent HMIs and door-status indication at the two opposite ends provide local operating information while the interlock preserves the barrier sequence.
Typical Applications
Decontamination processing of compatible bagged laboratory waste before removal from a containment suiteBarrier handling of cages, bedding and washable animal-facility components selected for moist-heat treatmentSteam processing of compatible glassware, culture media and laboratory utensils in microbiology facilitiesPass-through movement from a controlled hot side to a clean or service side under a site-developed cycle and release procedure
