About the Midmark Ritter M9 (2nd-Gen)
Description:
The second-generation M9 builds on Midmark’s long-running Ultraclave line with a re-engineered 9″-diameter, 15″-deep chamber that now survives 25 000 duty cycles—2.5 × the life of earlier models. A dynamic air-removal (steam-flush pressure-pulse) system and four factory-programmed gravity cycles (unwrapped, wrapped-270 °F, wrapped-275 °F, delicate-250 °F) are selected on a glove-friendly 5″ color capacitive touchscreen that also stores unlimited cycle records for the life of the unit. The microprocessor automatically fills, heats, vents, and dries; real-time alerts flag water level, filter, or gasket issues, while USB / Ethernet options simplify compliance reporting. Despite the automation, the M9 still slips onto a 20.5″-long countertop, draws a single 115 V/12 A circuit, and accepts Midmark’s familiar two-large/two-small tray set or five-slot pouch rack.
Economic Advantage:
Earlier bench-top autoclaves forced staff to babysit analog dials, log cycles by hand, and schedule chamber rebuilds every 10 000 loads. The 2-nd-gen M9’s touchscreen workflow, automatic documentation, and 25 k-cycle chamber cut labor and paper clutter, while its small 1.1-gal reservoir and low 12-A draw let clinics run multiple units on existing power without new plumbing. For a busy practice, those savings in staff minutes, service calls, and downtime translate into dozens more instrument sets sterilized—and billed—each week, delivering an ROI that rivals far costlier vacuum autoclaves.
