    STERRAD Systems offer simple, one-button operation with intuitive touch-pad controls and easy-to-follow prompts and instructions.

  3. What are the installation requirements for a STERRAD 50 System?

  6. What advantages do STERRAD Systems offer over peracetic acid, steam, and EtO systems?
    Using dry, low-temperature, gas plasma technology, STERRAD Systems provide a faster cycle time than EtO. Additionally, STERRAD Systems sterilize heat-stable as well as heat-sensitive and moisture-sensitive instruments. STERRAD Systems are also gentler on your delicate instruments, reducing instrument damage and repair costs, especially as compared with peracetic acid systems. Optimized speed and versatility increase the availability of ready-to-use instruments. Because they provide multiple advantages over steam and EtO systems, STERRAD Systems provide a greater return on investment.

    Importantly, STERRAD Systems do not produce harmful by-products, eliminating the need for aeration and ventilation. This makes STERRAD Systems safer for both operators and the environment.

  7. Can STERRAD Systems be used to sterilize instruments typically sterilized with steam or EtO?
    Yes. In fact, STERRAD Systems can be used to sterilize a wide range of instruments, including those sensitive to heat and/or to moisture. STERRAD Systems achieve a 10-6 SAL (Sterility Assurance Level) of packaged instruments.
