The programmable cryostat provides a gradient of "slow-controlled" cooling conditions during the dormant period of cell freezing. Compared with the liquid nitrogen-based programmable cryostat, the survival rate of cells frozen and thawed by the CRFT liquid nitrogen-free programmable cryostat is higher, and the accuracy, precision and reproducibility of cryopreservation can be guaranteed. Adopting Stirling engine technology without liquid nitrogen and refrigerant, the CRFT provides accurate and reproducible biological cryopreservation, which is suitable for cryopreservation of embryos, stem cells, mammalian cells, sperms, tissue sections and mandibulate organs.

The equipment allows for cryopreservation of embryos, stem cells, mammalian cells, sperm, antisomes, tissue sections and mandibulate organs, etc. It not only allows for precise control of cryopreservation and defrosting rates, especially at the critical nucleation/seeding stage, but also minimizes the risk of contamination.
