autoclave custom steam autoclave by priorclave

autoclaves for manufacturing by priorclaveThere is one way to be sure that your lab autoclave will reliably perform to your specification: Have it built to your specifications.  

Every Priorclave autoclave begins with a conversation. Our team will explore your sterilization needs, and help you determine the right configuration of the right model for your tasks, facilities, and requirements. Then that autoclave will be hand built, from start to finish, in our London factory.  

If you don’t need a steam jacket or powered door, then your autoclave won’t have one. If you do need enhanced cooling, filtration, monitoring, or another feature, it will be fitted.  Matching users to application-specific autoclaves doesn’t just reduce the purchase price of your autoclave by eliminating features of no use to you. It also results in a more reliable autoclave that costs much less to own, operate, and maintain.

At Priorclave, the safety of your staff and students, comes first. Priorclave is the only manufacturer offering the sophisticated Tactrol® 2 Control System on every model – benchtop to double-ender. Program cycles are simple push-button and/or keyswitch activated. Program modifications are keyswitch and/or password protected, and interface directly with your PC. The Tactrol 2 controller has the unique ability to be as simple as it needs to be, or as sophisticated as your process demands. Everything is within your control, and no additional training is required when moving from one unit to another. The Quickseal 2 door, with Permission-based Door Release, is fitted with thermal and pressure locks preventing opening of the autoclave at load temperatures above 80°C (176°F) and pressures above 0.2 Bar (2.9 psi) (BS2646).
