Provision of a Liquid Nitrogen Sample Storage Cryovial Store

The research department at Porton has a requirement to maintain an ultra-low temperature storage capability for biologicals (culture cells, bacteria, viruses) in liquid nitrogen tanks (Dewers). Following a review of the department a decision has been taken to replace the current unit with a new, more efficient unit. Therefore the requirement is for the replacement of an LN2 tank that can hold existing stocks that are checked and rationalised annually.
