A process and package product for preserving bacteriological culture media and gels is based on use of a sterilized air, liquid, and light impervious flexible wall pouch in which a Petri dish or similar device containing the medium or gel is stored and which is heat sealed after being evacuated and flushed with a inert gas to remove oxygen from within the dish and the pouch while in a vacuum chamber.

Method for preserving plated media and product

A conventional animal cage for housing experimental animals comprises a standard small animal shoe box with a filter bonnet modified with an auxiliary disposable sterile filter connected to a source of pressurized air so as to permit a forced circulation of air through the sterile filter and through an air filter sheet in the filter bonnet so as to permit only the exhausting of gases from the chamber.
