Small Vapor-Phase Liquid Nitrogen Tank

Product Overview

The small vapor-phase liquid nitrogen tank is a biological sample storage device that integrates cryogenic storage with intelligent monitoring. It is designed to provide safe and stable sample preservation under ultra-low temperature conditions.

The system adopts vapor-phase cryogenic storage technology and combines advanced liquid nitrogen container manufacturing techniques with an intelligent monitoring system to enable real-time monitoring and management of temperature, liquid level, and equipment operating status.

With its compact structure, lightweight design, and high storage efficiency, the equipment is well suited for storage environments where sample safety and stability are critical. The system can automatically monitor liquid nitrogen consumption and control refilling operations, while also supporting remote monitoring and data storage functions to improve the efficiency and intelligence of sample management.

The device continuously maintains a near ultra-low temperature vapor environment, reducing the risk of sample contamination. In the event of abnormal operation, the system can provide timely alarm notifications to ensure safe and reliable sample storage.

Working Principle

The small vapor-phase liquid nitrogen tank adopts a double-layer vacuum insulation structure. Multilayer insulation materials combined with high-vacuum technology form an efficient thermal barrier, reducing heat transfer from the external environment and minimizing liquid nitrogen evaporation loss.

Inside the container, the evaporation of liquid nitrogen creates a stable cryogenic vapor zone where samples are stored. This vapor-phase storage method prevents direct contact between samples and liquid nitrogen, significantly reducing the risk of cross-contamination.

The system is equipped with capacitive liquid level sensors and temperature monitoring devices to continuously monitor liquid nitrogen levels and temperature variations. An automatic control system manages liquid nitrogen refilling and equipment operation. In addition, the device supports remote communication and data recording functions, enabling continuous data backup and analysis.
