All Priorclave autoclaves comply with current US, Canada, UK, and EU safety regulations, and are manufactured under an ISO 9001:2008 quality management system. All pressure vessels are manufactured in-house and tested to 1.5 times their maximum working pressure. They have full Insurance approval for pressure vessel design and construction and are CE Marked under the Pressure Equipment Directive PD5500:2000 Cat 3, Certificate Number SS42059010-2 Rev 1. They also conform to the general requirements of BS2646 and are CE Marked for BS EN61010-2-41, Low Voltage and Electromagnetic Compatibility.

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).

The door is also fitted with a Redundant Safety Gate, allowing potential residual pressure to safely escape before the door can be fully opened (in accordance with the UK Health and Safety Executive’s note PM73).  Fitted with a Pressure Safety Valve set to 2.5 Bar (36.3 psi) and a 150°C (302°F) thermal cut out (BS6759); selected external panels and surfaces are Thermally Insulated.  All front loading models are fitted with non-tip shelves.
