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

Pass-through autoclaves enable sealed laboratory environments to be maintained, with door interlocks preventing potential for laboratory standards to be compromised. Every double-door autoclave provides a sterile path in and out of sealed laboratories.

At one time, double-door autoclaves were relatively rare. But over recent years we’ve seen ”clean room” high-containment practices adopted in a wide variety of industries, ranging from biomedical research to semiconductor fabrication. While other laboratory autoclave manufacturers are new to this field, Priorclave has been here all along. We offer a variety of flexible pass-through (double-ended) 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 to your laboratory specifications. Because our steriliser 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, stainless steel loading shelves and doors, and so on. If you purchase vacuum options, the steriliser is capable of both pre-vacuum and pulsed freesteaming cycles. Autoclave chambers can range from 150 litres to 700 litres in volume, depending on the requirements of your laboratory. Our pass-through autoclaves are front loading, and have round and rectangular chambers.

Our autoclaves come equipped with the Tactrol® 2 Control System, which provides both safety and efficiency features as well as enabling you to automate the sterilisation process. This includes automatic timed freesteaming, which improves air removal and sterilising performance. 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. The panel can provide visual feedback for where the autoclave is in the sterilisation cycle (vacuum, media warming, cooling, etc.). 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-sterilisation 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. Our double- door autoclaves also feature epoxy coated panels and frame members which are treated with an anti-bacterial agent which is effective against all bacteria and fungi including MRSA.

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

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.
