Indications for Use

The Midmark and Ritter M9 and M11 UltraClave® Automatic Sterilizers and the Ritter M9D AutoClave® Automatic Sterilizer can be used in medical and dental offices, hospitals, clinics, nursing homes, laboratories, and other facilities to sterilize heat and moisture stable reusable items (including dental handpieces) that are compatible with steam sterilization.

Device Story

Self-contained tabletop steam sterilizers; utilize steam-flush pressure-pulse (SFPP) technology to remove air from chamber and processed materials. Inputs: user-selected cycle (Unwrapped, Pouches, Packs, Handpieces) via front panel keypad. Operation: microcontroller-controlled; uses immersion heater to generate steam; sensors (platinum RTD for temperature, pressure transducer) monitor cycle parameters. Outputs: sterilized items; visual status/error codes on LCD; optional thermal printer records cycle stats (time, temp, pressure). M9/M11 models feature automatic door opening for drying; M9D requires manual door operation. Used in clinical/dental settings by staff to ensure instrument sterility; benefits patient by reducing risk of cross-contamination.

Clinical Evidence

No clinical data. Bench testing performed per ANSI/AAMI ST55:2010/(R)2014. Validation included thermal profiling of empty chambers and biological indicator (BI) testing using Geobacillus stearothermophilus (1.0 x 10^6 spores) in fully loaded chambers to confirm a Sterility Assurance Level (SAL) of 10^-6.

The M9 UltraClave models include a variation designated as the M9D Autoclave, the only difference being that the M9 UltraClave includes a motor to automatically open the door for drying and the M9D Autoclave is a manual model which requires the operator to open the door for drying. They are self-contained devices that are electrically powered with automatic controls for controlling time and temperature that are designed for safe, easy operation with minimal operator training. {7}------------------------------------------------ The Midmark and Ritter M9 and M11 UltraClave and RitterM9D AutoClave Self-Contained steam sterilizers have an overall chamber dimension / volume size of 9" (22.9 cm) x 15" (38.1 cm) / 0.47 ft (13.4 L) for the M9 and 11" (27.9 cm) x 18" (45.7cm) / 0.87 ft (24.6 L) for the M11. The steam sterilizers operating temperatures of the preset cycles are 250°F +6°F/-0°F (121°C +3°C/-0°C) and 270°F +6°F/-0°F (132°C +3°C/-0) which utilize a steam-flush pressure-pulse (SFPP) cycle consisting of three (3) or four (4) sequential steam flushes and pressure pulses to remove air from the sterilizing chamber and processed materials. SFPP cycles rely on diffusion of residual air in the steam and subsequent flushing of the air-steam mixture from the sterilizer resulting in shorter cycle times than gravity displacement sterilizers. Air removal is achieved with the sterilizing chamber pressure at above atmospheric pressure. The operation of the sterilizer is controlled by a software controlled microcontroller internal to the unit. The software provides for user control of the device via a keypad on the unit's front panel. The same software is used for the Midmark and Ritter M9 and M11 UltraClave" and Ritter M9D AutoClave® Self-Contained Steam Sterilizers. Image /page/7/Picture/3 description: The image shows a front panel of a machine with several buttons and a display screen. The display screen reads "SELECT CYCLE". There are buttons labeled "P", "1", and "2", as well as buttons with icons representing "Unwrapped", "Pouches", "Packs", and "Handpieces". There are also green "Start" and red "Stop" buttons.
