100L - 400L Autoclave
Front-Loading

A front-loading autoclave with a traditional cylindrical vessel is the best option available for research, education, and quality assurance facilities. A cylindrical chamber is better suited to high pressure micro-environments, requires less reinforcement and insulation, and suffers less wear and tear over the life of the autoclave. Each of our front-loading autoclaves is entirely custom built to your specifications, in terms of temperature and pressure levels as well as chamber size. A lower parts count, more efficient steam generation, lean cylindrical pressure vessel, and application-specific build don’t just reduce the purchase price: It results in a more reliable autoclave that costs much less to own, operate, and maintain.

Product Description

If you don’t need to sterilise flat trays of medical instruments, then you don’t need a rectangular-chamber medical steriliser-and don’t want one. On an annual basis, a cylindrical-vessel front-loading autoclave can be expected to use 1/6th to 1/10th as much water and energy as a comparable rectangular model autoclave—that’s added savings on top of the lower initial purchase price.

The advantages inherent in using a cylindrical-vessel sterilizer become especially apparent with large-volume front-loading autoclaves. By eliminating corners, the cylindrical vessel improves steam circulation, preventing cold pockets and assuring complete sterilization without excessive cycle times or chronic failed loads.  Our largest models go head-to-head with comparable conventional rectangular autoclaves, offering similar cycle times with lower maintenance burdens and substantial energy, water, and lifetime cost savings. Popular with community colleges, research facilities (small and large), universities, testing labs, and industrial operations.

Our front-loading sterilisers feature the programmable Tactrol Control System that allows for automatic steam sterilisation with precise custom cycles and one-touch simplicity. The external panels of the steam autoclave have Biomaster Protected® Antimicrobial Surfaces to help defend against cross-contamination by bacteria, mold, and mildew. The autoclave chamber and door are made of ASME-certified 316L stainless steel for increased durability and reliability.

If your lab needs to sterilise very tall flasks, fermentors, or bioreactors, Priorclave also offers vertical autoclaves that load from the top. If you’re not sure whether loading from the top or loading from the front makes more sense for your lab, contact us and one of our seasoned experts can help you figure this out. Priorclave can find the right laboratory autoclave for your team, with options ranging from small chamber volume benchtop autoclaves to larger pass-through autoclaves.
