    Incredible thanks to

    • EliSense: Thanks to LED indicators and display the outstanding technology offers cycle status information, temperature information and much more to optimize both workflow and output at a glance.
    • EliTrace: For the first time, the sterilization process can be traced and documented down to the individual instrument or instrument kit. Without additional software or computer.
    • Eco Dry+: Eco Dry technology adapts the drying time to the mass of the load. This reduces the cycle time, increases the life span of your instruments and optimizes the energy consumption.
    • Intuitive interface
    • Perfect ergonomics
    • New environmentally friendly packaging
      The new environmentally friendly packaging is completely reusable and recyclable. Plastic components were reduced to a minimum. For 99% of its weight, the new package is made of cardboard and other fully biodegradable substances.
