150L - 700L Autoclave
Double-Door / Pass-Through

At one time, double-door “pass-through” autoclaves were relatively rare. But over recent years we’ve seen ”clean room” containment practices adopted in a wide variety of industries, ranging from biomedical research to semiconductor fabrication. While other autoclave manufacturers are new to this field, Priorclave has been here all along. We offer a variety of flexible pass-through choices with all of the sophisticated containment and safety features you expect from units twice as expensive. Our pass-through autoclaves are used in universities, mobile military facilities, BSL-3 containment suites, and research labs dedicated to West Nile and avian flu, pharmaceuticals, entomology, industrial product development, and more.

Product Description

Every Priorclave pass-through autoclave is entirely custom built in our London factory to your specifications.  Because units are all built-to-suit, we can accommodate an almost unlimited number of design considerations specific to your applications and facility: Chamber size, steam source, wall thickness, door swing, and so on. The Tactrol control panel can be mounted either inside or outside the containment area (depending on the application), as can any data ports or the hardware printer. Pressure interlocks, thermal safety locks, and double-door interlock mechanisms prevent any inadvertent cycle disruptions or breaching of containment integrity. We regularly outfit our BSL-3 (biosafety level 3) pass-through autoclaves with Effluent Retention systems, which include condensate re-sterilization and 0.05 micron filters in the vent outlet (capable of capturing organisms as small as viruses). These are required by law in some biosafety contexts, but also valuable in non-BSL settings where waste loads are frequently processed.

Air Intake Filter System

Protects sensitive loads from contamination from the outside air drawn in as the autoclave cools.

Close

Auto-waterfill

Automatically re-fills the autoclave chamber while the door is open ready for the next cycle. Requires a water supply. (Fitted as standard to electrically heated vacuum models)

Close

Calibration

As a UKAS accredited Laboratory Priorclave can provide annual or bi-annual calibration of your autoclave at one or more temperatures. Following successful calibration a UKAS certificate is issued.

Close

Cycle Repeat

Particularly useful for product testing, this option allows the autoclave to run one cycle after the other without stopping. The total number of cycles can be set from the control panel. For electrically heated Priorclaves a water supply is required. (Not suitable for Distilled, Ultra Pure or RO water supplies.)

Close

Air Ballast System

Controls distortion of semi-rigid containers, pouches and blister-packs as the autoclave cools by pressurising the autoclave chamber with air, balancing the internal pressure inside the containers, pouches or blister packs. In autoclaves with water cooling jackets it controls volume losses when rapidly cooling liquid loads. Requires an extremal air supply at a minimum pressure of 3 BarG.

Close

Accelerated Media Cooling

Accelerated Media Cooling – can reduce cooling times for liquid loads by up to 50% (Depending on load size and type volume loss may exceed 5%). Requires a minimum 5 program memory and Performance testing to set up the cycle parameter. Includes an air intake filter.

Close

Adaptation for special water supplies.

Electrically Heated Priorclaves require soft water with a conductivity of a minimum of 100 micro Siemens to work correctly. Various adaptations can be made to pipe work, fittings and water detection systems for Ultra pure water supplies if required.

Close

Additional Options Kit for Health Service Customers

Includes Tactrol Self Monitoring, Mechanical Cycle Counter and other options according to model to assist with the requirements of some health service installations.

Close

Air Ballasting with built-in air compressor

Controls distortion of semi-rigid containers, pouches and blister-packs as the autoclave cools by pressurising the autoclave chamber with air, balancing the internal pressure inside the containers, pouches or blister packs. Includes a quiet running air compressor mounted, where possible, inside the autoclave body.

Close

Condensate Collection Bottle

Where a drain is not available the autoclave exhaust is collected outside the autoclave for periodic disposal. Not suitable for vacuum models or sterilising waste / discard loads.

Close

Customer requested Pressure Vessel Approval

Form X Pressure Test Certification – Individually witnessed Hydrostatic Test with stamped certificate. MUST be requested at time of purchase.

Close

F0 Integration

Reduces overall cycle time by including time spent at high temperatures during heating and cooling in each cycle. Most suitable for standard, repeated loads.

Close

Factory Acceptance Test

Factory Acceptance test carried out with the customer at Priorclave’s factory after manufacture and before despatch.

Close
