Abstract
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.
