Title:
METHOD AND SYSTEM FOR CONTROLLED RATE FREEZING OF BIOLOGICAL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2009/062025
Kind Code:
A3
Abstract:
A method and system for controlled rate freezing of biological materials is provided. The presently disclosed system and method provides the ability to rapidly cool the biological materials contained in vials or other containers within a cooling unit via forced convective cooling using a laminar and uniform flow of cryogen in proximity to the plurality of vials disposed within the cooling unit. The rapid cooling of the biological materials is achieved by precisely controlling and adjusting the temperature of the cryogen being introduced to the system as a function of time.
