Abstract
An apparatus for sterilizing or disinfecting a device has a chamber, a source of sterilant or disinfectant and ports for admitting and exhausting the sterilant or disinfectant but lacks a source of sterile rinse. A related method similarly lacks the step of rinsing with a sterile solvent yet leaves the device essentially free of the sterilant or disinfectant. Preferably the sterilant or disinfectant is removed from the device by vaporizing it and drawing it out of the chamber.
