Technical Specifications of the Midmark Ritter M11 Autoclave

Capacity and Chamber Size

• Volume: 28.3 liters (7.5 gallons)
• Chamber Dimensions: 279 mm diameter x 457 mm depth (11 inches x 18 inches)

This capacity is suitable for small to medium-sized loads, making the Midmark M11 ideal for dental practices, small clinics, and laboratories that require efficient sterilization of instruments and equipment. The M11 model ensures reliability and high performance in various medical and laboratory settings.

Temperature Range

• Operating temperature ranges from 110°C to 135°C (230°F to 275°F).

These temperatures are sufficient to ensure the destruction of a wide range of microorganisms, including highly resistant bacterial spores. The M11 sterilizer operates by using saturated steam to denature proteins and disrupt cellular structures, ensuring effective sterilization. The Ritter M11 sterilizer is designed to handle these high temperatures, making it a reliable choice for thorough sterilization.

Pressure Range

• The working pressure range is approximately 1.0 to 2.2 bar (14.5 to 32 psi).

Pressure is a critical component in achieving the necessary high temperatures for sterilization. The Midmark M11 utilizes increased pressure within the chamber to raise the boiling point of water, allowing the steam to reach higher temperatures and penetrate materials more effectively. The Ritter M11 autoclave ensures efficient and thorough sterilization through this advanced pressure mechanism.

Cycle Types and Control System

• Pre-set Cycles: The Midmark Ritter M11 features several pre-programmed cycles tailored to different types of loads, such as wrapped instruments, unwrapped instruments, packs, and liquids.
• Customizable Cycles: Users can customize cycles to meet specific sterilization needs, adjusting parameters such as temperature, pressure, and duration.
• Control System: The autoclave is equipped with a microprocessor control system that accurately manages the operating parameters. The digital interface provides real-time monitoring and adjustments, ensuring precise control over the sterilization process.

Safety Features

• Automatic Shut-off: The autoclave automatically shuts off at the end of the sterilization and drying cycles to prevent overheating and overuse.
• Safety Valve: Prevents over-pressurization by releasing excess pressure, thereby protecting the system and ensuring user safety.
• Door Safety Lock: Ensures that the door cannot be opened while the chamber is pressurized, preventing accidents and ensuring safe operation.

Construction

• Materials: The autoclave is constructed from high-quality stainless steel, which provides resistance to corrosion and ensures durability under high-pressure and high-temperature conditions.
• Design: The compact design facilitates efficient use of space and ease of operation, with an intuitive loading and unloading process.

Principles of Operation

Sterilization by Saturated Steam

• Mechanism: The primary sterilization method used by the Midmark Ritter M11 involves saturated steam under pressure. The steam transfers heat to the items within the chamber, and the combination of high temperature and moisture denatures proteins and disrupts cell membranes and DNA, leading to effective sterilization.
• Temperature and Pressure Correlation: The autoclave operates on the principle that water boils at higher temperatures when under increased pressure. By raising the pressure within the chamber, the boiling point of water (and thus the temperature of the steam) increases, enabling the steam to achieve the necessary conditions for sterilization.

Microprocessor Control

• Function: The microprocessor control system manages the cycle parameters (temperature, pressure, and time) with high precision. It receives input from sensors within the chamber and adjusts the heating elements and valves to maintain the desired conditions.
• Advantages: This control system enhances the repeatability and reliability of the sterilization cycles, ensuring consistent performance and effective sterilization across different loads and materials.

Heat Transfer and Moisture Penetration

• Heat Transfer: Effective sterilization requires uniform heat distribution. The autoclave’s design ensures that steam circulates throughout the chamber, transferring heat to all surfaces of the items being sterilized.
• Moisture Penetration: Moist heat (steam) is more effective at penetrating materials than dry heat. The steam condenses on cooler surfaces, releasing latent heat and ensuring thorough sterilization of complex instruments and porous materials.
