The British Compressed Gas Association has issued a revision to its Code of Practice 45, covering biomedical cryogenic storage systems and their design and operation.

The document details the design, installation and operation of systems used for the storage of biomedical materials at cryogenic temperatures, using liquid nitrogen as a sacrificial refrigerant.

CP 45, is set to replace the existing BCGA GN 19 code, ‘Cryogenic sample storage systems (Biostores). Guidance on design and operation’, set to be withdrawn upon publication of CP 45.

The newly replaced document can be downloaded free of charge from the publication area of the BCGA website.
