Cryo.s are for storage of tissue, cells, fungi,bacteria, spores, cellular extracts or body fluids at ultra-low temperature for research and development purposes in avery compact format. They must not be stored in the liquid phase of liquid nitrogen, but only in the gas phase above. Cryo.s tubes are not intended for any application in the context of reproductive medicine.
An outstanding feature of all Cryo.s is the utilisation of a USP class VI certified, medical grade polypropylene for tube manufacturing. This material does not release significant amounts of leachables, hence stored samples stay clean and free of contamination. Sterile product versions are sterilised applying an ISO 11137 validated irradiation procedure yielding an SAL level of 10 – 6.
The portfolio of Cryo.s tubes includes cryogenic tubes with different volumes, different base forms as well as several cap colours. Cryo.s offer several features for the identification and labelling of individual samples, to include coloured screw caps, a white, scratch-resistant writing area and barcoding options.
