Title:
ACCESSIBLE COOLING SYSTEM, ESPECIALLY FOR CRYOPRESERVING BIOLOGICAL SAMPLES, AND METHOD FOR THE OPERATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/104080
Kind Code:
A3
Abstract:
A cooling system (1), especially for cryopreserving biological samples (2), comprises a cooling chamber (100) delimited by a bottom area (110), side walls (120), and a top area (130), and a cooling device (200) for cooling the cooling chamber (100) using liquid nitrogen (220). The bottom area (110) is designed for direct cooling using the liquid nitrogen, and the cooling chamber (100) is dimensioned such that an operator (3) can access and move around in the cooling chamber (100). The bottom area (110) has a platform (111) which is permeable to vapor of the liquid nitrogen (220) and forms a support zone for the operator (3). Methods for operating the cooling system are also described.
