INTENDED USE AND PRECAUTIONS
This equipment is designed for low temperature storage of human cells, organs, plasma and DNAs.
The effective storage period depends on the sample condition and storage temperature. It is
necessary to determine the storage temperature and period suitable for the purpose.
For the live cells, the lower storage temperature should be required for long term storage. It is
recommended to store the live cells at -130
℃
or lower.
