Technical Specifications of the Tuttnauer EZ9 Autoclave

Capacity and Chamber Size

  • Volume: 19 liters (5 gallons)
  • Chamber Dimensions: 230 mm diameter x 470 mm depth (9 inches x 18.5 inches)

This capacity is suitable for small to medium-sized loads, making it ideal for dental offices, small medical practices, and laboratories that require efficient sterilization of instruments and equipment. The Tuttnauer EZ9 autoclave is another excellent option for reliable and effective sterilization in similar settings.

Temperature Range

  • Operating temperature ranges from 105°C to 137°C (221°F to 279°F).

These temperatures ensure the destruction of a wide range of microorganisms, including highly resistant bacterial spores. The autoclave operates by using saturated steam to denature proteins and disrupt cellular structures, ensuring effective sterilization.

Pressure Range

  • The working pressure range is approximately 0.7 to 2.5 bar (10.15 to 36.25 psi).

Pressure is a critical component in achieving the necessary high temperatures for sterilization. By increasing the pressure within the chamber, the boiling point of water is raised, allowing the steam to reach higher temperatures and penetrate materials more effectively.

Cycle Types and Control System

  • Pre-set Cycles: The Tuttnauer EZ9 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 fully automated 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.


  • 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 Tuttnauer EZ9 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.

Automated Control System

  • Function: The automated 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.
