Liquid nitrogen cryogenic freezers

This liquid nitrogen cryogenic storage system is a core piece of equipment for the large-scale long-term preservation of biological products in biomedical and research institutions. It employs a partially open tank structure and vacuum multi-layer insulation technology, specifically designed for the long-term ultra-low temperature static storage of biological samples such as stem cells, plasma, semen, and embryos. It is a key supporting equipment for biobanks, laboratories, and medical institutions.

The equipment boasts a large storage capacity. The tank is made of high-strength stainless steel, combined with the latest vacuum multi-layer insulation technology, providing excellent liquid nitrogen insulation performance. This effectively reduces evaporation loss and achieves long-term stable ultra-low temperature preservation of biological products. It also integrates electronic temperature control and liquid nitrogen dispersion technology, ensuring uniform and stable cooling and temperature control within the equipment, avoiding damage to biological samples caused by localized temperature differences. It offers both immersion storage and gas phase storage modes, which can be flexibly switched according to sample type and preservation requirements, adapting to the storage standards of different biological products such as stem cells, plasma, and embryos.

In terms of operation and safety, the equipment design balances convenience and reliability: the intelligent control system simplifies operational procedures such as liquid nitrogen replenishment and temperature adjustment, allowing for basic maintenance without the need for professional personnel; equipped with multiple safety devices including liquid level monitoring, over-temperature alarms, and pressure protection, it ensures the safety of sample storage throughout the process; the static storage structure design of the tank further reduces the risk of sample disturbance during preservation.

Core Application Scenarios:

1. Long-term storage of stem cells and immune cells in biobanks

2. Cryopreservation of plasma and blood products in hospital blood banks

3. Storage of reproductive samples such as semen and embryos in livestock institutions

4. Cryopreservation of tissue samples and biological reagents in research laboratories

Whether for the construction of sample banks in the biomedical field or the preservation of biological resources in research institutions, this liquid nitrogen cryogenic storage system can meet the professional needs of long-term cryogenic storage of biological products with its large capacity, high stability, and multi-mode characteristics.
