Safety Features

The autoclave lids are designed with a number of independent mechanical and digital safety features.

  • A safety device prevents the operator from opening the door when the chamber is pressurized
  • A cycle cannot start if the door is open or not properly locked
  • The door cannot unlock until chamber pressure reaches room pressure
  • Safety Valves: The chamber is equipped with safety valves – if the pressure exceeds the allowed limit the safety valves will discharge
