A process for concentrating hydrogen peroxide from a relatively dilute solution of hydrogen peroxide and water and supplying the concentrated hydrogen peroxide in vapor form to a sterilization chamber. The process includes vaporizing a major portion of the water from the solution and removing the water vapor thereby produced before injecting the concentrated hydrogen peroxide vapor into the sterilizing chamber.

Vaporization method to enhance sterilant penetration

A process for sterilizing and depyrogenating a pretreated solution, such as water, by adding an oxidant selected from the group consisting of hydrogen peroxide and ozone and heating the solution and the oxidant to a temperature sufficient to sterilize and depyrogenate the solution for a period of time, preferably less than 5 minutes. The oxidant is thereafter removed and the sterilized, depyrogenated solution is cooled for dispensing.
