Ritter Midmark M11 Autoclave Brochure


This is the older Version of the M11 and does not have the same digital display as the new unit.

With one of the largest chamber sizes of any tabletop sterilizer on the market, the Ritter M11 is designed to optimize sterilization output—reducing time and effort, but not effectiveness.


The M11’s 11″ x 18″ chamber gives it the distinction of being the largest of any standard countertop sterilizer on the market, making it perfect for larger packs and instruments.

  • Steam–Flush Pressure Pulse Air Removal System ensures proper steam penetration
  • Simply load it, set it and forget it
  • Four pre-programmed and two programmable cycles
