The Ritter / Midmark M11 Ultraclave features one of the largest chamber sizes of any tabletop sterilizer on the market, and is designed to optimize sterilization output. This reduces time and effort, but not the effectiveness of the sterilizer. The M11 UltraClave’s’ 11″ x 18″ chamber gives it the distinction of being the largest of any standard counter top sterilizer on the market. This makes it perfect for larger packs and instruments.  The Steam–Flush Pressure Pulse Air Removal System ensures proper steam penetration throughout the chamber. The M11 is easy to use – simply load it, set it, and forget it! And the M11 is convenient too,  with four pre-programmed and two programmable cycles.  Other features of the Midmark M11 UltraClave include:
  • Open-Door Drying – once sterilization is complete, the door opens automatically and quietly to dissipate steam and dry your instruments
  • Programmed Controls -once a pre-programmed cycle is selected, the unit is designed to automatically sterilize without any operator assistance
  • Smart Technology – if the door isn’t closed completely or the water level is low, the sterilizer will stop and alert the operator to take proper action
