The M11 UltraClave is a self-contained, countertop steam sterilizer. The 22.9-cm diameter sterilizer chamber offers the option of utilizing two 23 x 38-cm and two 17 x 38-cm trays, four standard instrument cassettes, or a pouch pack. The sterilizer has preprogrammed cycle settings as well as programmable controls for time, temperature, drying time, and vent. An LCD display shows the settings and cycle status. Sterilization cycles range from 18 to 44 minutes depending on whether instruments are unwrapped or placed in pouches or packs. Drying time of 0 to 60 minutes can be selected. At the end of each cycle, the door opens automatically and quietly. Measuring 58-cm deep x 46-cm wide x 46-cm tall, the M11 UltraClave weighs 45 kg (99 lb) and requires either 100V/15A or 220V/10A for operation. Water reservoir capacity is 1.4 gallons. Ten consultants evaluated the M11 UltraClave over a period of six months. This product received a 96% clinical rating.
