Since 1969 Andersen's low temperature 100% ethylene oxide (EtO) sterilizers have saved instruments from sterilization damage and prevented the spread of superbug infections. EOGas® and Anprolene® Sterilizers employ a single dose of EtO, and the lowest on the market, in a flexible plastic chamber. Andersen offers operator training to support you and your employees. We also offer contract sterilization services and lab testing. Installing an Andersen Sterilizer is simple, just a vent to the outside and a standard power supply is all that is required.
