The operation of the cryobank for long-term storage of samples in liquid nitrogen started in March 2016 and the cryobank is divided into two parts. The first part is situated in the main building of the BIOCEV Centre and is mainly intended for storage of cell lines and hybridomas. The second part is located in building SO-002 as a component of the transgenic and archiving module. This part of the cryobank mainly serves for preservation of mouse sperm and mouse embryos in liquid nitrogen or its vapours.
The storage containers (LABS40K, LABS80K – Taylor-Wharton and 24K) are connected to an external reservoir for liquid nitrogen with a capacity of 10,000 litres and are refilled automatically. The cryobank also includes four filling sites providing the possibility to draw liquid nitrogen into both pressure and non-pressure containers. The entire cryobank system is connected to a back-up power supply for the cases of power outage. All operations, diagnostics and checking of the liquid nitrogen level in the storage containers are fully automated and controlled. The parameters (temperature, humidity, O2 concentration) and the safety in both the cryobank and the storage containers themselves are controlled by a monitoring system connected to GSM and a web interface.
The cryobank core facility also administers production of dry ice.
