Fully Automatic Autoclaves

Sterilization is made easy by the Midmark Ritter M9 Autoclave. Simply press the Start/Standby button and this autoclave will fill itself with the appropriate amount of water automatically. Once the autoclave is filled with water, select your cycle and the M9 will set the time for you. Cycle time from start to finish is 22 minutes (if cold) and 12 minutes (if hot).


  • Low water indicator light tells you when the reservoir level is too low
  • A door-ajar light tells you if the door is not securely closed
  • LED display shows the units temperature during heat-up and time remaining during cycles.
  • Lights turn on progressively during filling, heating, sterilizing, drying and complete stages.
  • Easy to fill and to drain water – located at the front of the machine
  • A large capacity water reservoir means you fill it less often!
  • Four stainless steel trays come with the unit (two large, two small)
  • Easy-to-read pressure gauge and electronic controls offer simple operation and reduce downtime.

    These autoclaves don’t even look refurbished, they are basically brand new. Great deal – would recommend
