Liquid Nitrogen Biobank

Product Overview

The liquid nitrogen biobank is an ultra-low temperature storage system designed for the long-term preservation of biological samples. It is widely used in biomedical research, medical institutions, and biological resource management facilities. The equipment is manufactured using specialized stainless steel materials for cryogenic applications and incorporates an advanced insulation structure, ensuring both stable ultra-low temperature conditions and excellent structural durability.

This type of biobank integrates intelligent functions such as temperature monitoring, liquid level monitoring, automatic refilling, and alarm management. These systems allow continuous monitoring of operating conditions, ensuring the safety and stability of stored samples. The wide-mouth opening and hinged lid design make sample access more convenient and efficient while minimizing temperature fluctuations during operation.

The system supports both vapor-phase and liquid-phase storage modes. Even during extended lid opening, the internal temperature can remain stable and evenly distributed. By optimizing internal space and insulation design, the equipment reduces liquid nitrogen consumption while increasing storage capacity, providing an efficient and reliable cryogenic solution for biological sample management.

Working Principle

The liquid nitrogen biobank adopts a double-layer vessel structure. The inner container is used for storing liquid nitrogen and biological samples, while the outer container provides mechanical protection and forms an insulated space. Between the two containers, a high-vacuum environment combined with multilayer insulation materials creates an efficient thermal barrier, significantly reducing heat transfer from the external environment and minimizing the evaporation rate of liquid nitrogen.

Inside the system, the evaporation of liquid nitrogen generates a stable ultra-low temperature environment that enables sample storage in either vapor-phase or liquid-phase conditions. Vapor-phase storage prevents direct contact between samples and liquid nitrogen, reducing the risk of cross-contamination while maintaining a consistent cryogenic environment.

The system is equipped with built-in temperature sensors and liquid level detection devices that continuously monitor operational conditions. If abnormal changes in liquid nitrogen level or temperature occur, the monitoring system can immediately trigger alarm notifications. In addition, the equipment supports remote monitoring and data recording functions, enabling intelligent management of the sample storage process.
