System and Methods for improvements to a Ultra-low temperature bio-sample storage system

摘要

This application uses technology found in existing patents U.S. Pat. No. 7,823,394 and U.S. Pat. No. 7,621,148B1. The application solves the problem of internal icing within bio-sample storage freezers by introducing three new techniques to traditional mechanical freezers. Highly effective hybrid insulation technique, Internal purging using water vapor free air and Close tolerance fitment of internal sub-assemblies.

主权项

1. A method for storing bio-samples, comprising:
introducing a positive pressure of desiccated air into a storage area of a freezer and an interstitial area between compartment doors and a main door; applying effluent and purging the interstitial space and a payload bad behind inner doors; and conditioning incoming ambient air using a triple level of filtration.
