Method for preserving plated media and product

摘要

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.
