The Midmark Ritter Ultraclave M11 Automatic Sterilizer Autoclave uses sophisticated and intuitive technology to optimize the sterilization process and kill dangerous microbes, to ensure clean and sanitary tools for your patients. This is the largest Midmark Autoclave.

Boasting THE LARGEST midmark size, at an impressive 11”x18” sterilization chamber, one of the largest desktop sterilizers on the market, the Midmark Ritter Ultraclave M11 can sterilize multiple items and oversized pouches effectively and efficiently. The Midmark M11 is our #1 autoclave for sale.

The Midmark M11’s easy-to-use pre-programmed controls allow you to sterilize unwrapped, pouched, packed, and handpiece equipment with the touch of a button. The self-programming option allows you to customize exposure time, temperature, dry time, and vent, and save your preferences for future one-touch use. The Midmark M11 is the largest autoclave to come from the Midmark Corporation

Inbuilt safety features provide peace of mind during the sterilization process, and the Midmark Ritter Ultraclave M11 Automatic Sterilizer Autoclave has an easy-to-read liquid crystal display (LCD) display panel that warns you of low water levels or if the door is not fully closed.

By having the reservoir fill port and drainage tubes located in the front of the sterilizer rather than the top or back, water can easily be topped up and drained with minimal spillage or mess, keeping your surface area clean and hygienic. Buy the autoclave ultraclave m11 today.
