For cryopreservation, temperature control is critical because the material you store is invaluable. Liquid nitrogen is an ideal cryogen for keeping biological samples fresh for effectively indefinite periods. Nitrogen’s ultracold temperature maintains long-term viability of cell structure and helps improve reliability, since the systems are not susceptible to electrical outages.
