Our Refurbished Midmark Autoclaves/Ultraclaves are Always the Newest Style!

This AUTOMATIC Midmark Ritter Ultraclave M9 Sterilizer Autoclave uses cultivated steam technology to remove harmful bacteria and provide a thorough sterilization process for your examination tools.

While scaled back in size, the compact 9”x15” chamber provides robust power for offices with limited space available. Four trays, two large and two small, hold multiple items inside the chamber, letting you sanitize various tools in one cycle.

Simply choose between the four pre-programed cycles or two customizable cycles, press start, and let the Midmark M9 Sterilizer do the work for you. The timer will be automatically set and the proper amount of water required for the chosen cycle will be released. The steam created will encase each tool in the chamber using a steam-flush pressure pulse air removal system.

Once the sterilization is complete, a sound will emit from the Midmark M9D alerting the operator to open the door and remove the contents from the chamber. This signal removes the need to remain by the equipment, allowing you to load your tools, select your cycle, and move on to your other tasks. Perfect for a busy medical practice.

Safety features of the Midmark Ritter Ultraclave M9 Sterilizer Autoclave provide peace of mind during the sterilization process, and the machine has an easy-to-read liquid crystal display (LCD) display panel with lights that convey water levels and proper door closure.

The Midmark M9 has a reservoir fill port and drainage tubes at the front of the sterilizer, allowing water to be filled and drained easily, which helps keep your surface area dry and hygienic.

The Midmark Ritter Ultraclave M9 Automatic Sterilizer Autoclave also has available compatible accessories, including an impact printer and pouch rack to maximize sanitation and infection control.
