After more than 15 years away, Andersen Sterilizers returns to the healthcare market, launching its newly released EOGas 4PLUS sterilizer featuring breakthrough EO-Flexible Chamber technology. Lethal enough to kill pathogens, but gentle on complex devices, EOGas 4PLUS is the only system in the world FDA-cleared to terminally sterilize the longest endoscopes, including those that have 1100 mm working lumens.
