Deep cold liquefied (cryogenic) gases like nitrogen, oxygen, argon, hydrogen and helium are used in industry – for example in the fields of chemistry, aerospace – as well as in medicine and research. In order to store and apply them, insulated vessels and piping is required to reduce evaporation losses.
The long-term storage of medical, biological and ecological samples at temperatures of approximately -130°C in the gas phase in so-called cryobanks has been state-of-the-art technology for some time. The goal is to store valuable samples for a long time and to keep them unchanged. Due to its inert character, liquid nitrogen (boiling point -196°C at ambient pressure) serves as a cooling agent. For larger sample quantities, vacuum super-insulated storage vessels are amalgamated to a cryobank.
In order to fulfil the high requirements of this application area Cryotherm offers the system series BIOSAFE®-MDß and -SCß. BIOSAFE®-Systems with the addition MDß are medical products of class ll2a according to the EU-directive, the addition SCß designates the standard version. Storage systems always have to be medical products when the samples stored are intended for re-introduction to human beings (for example with blood or sperm).
