Cryogenic Freezer, LN2 Vapor Phase

CryoMatrix series high-efficiency vapor phase liquid nitrogen storage system provides the most ideal storage

conditions for biological samples. The whole series realize -190°C vapor phase storage. Supported by LN2

automatic filling system and temperature & LN2 level monitoring system, CryoMatrix freezers provide all-round

protection to precious sample, assisting life science research and cell therapy applications. Based on the actual

needs of users, Antech has innovatively optimized the performance, structure and control system of the

vapor-phase cryogenic freezer to meet the user's highest standard of large-capacity vapor-phase cryogenic storage requirements.

Advanced Control System

1.HMI human-machine interactive touch screen, display temperature, liquid level, temperature curve and alarm information.

2.Important events such as temperature, alarm, liquid nitrogen fill, can be checked, and can also download through USB disk.

3.Various alarms, and the alarm information can be stored and downloaded through the USB disk. 

4.Operating data, such as temperature and liquid level, can be stored for up to 10 years.

5.Optimized structure design to achieve the best sample storage density and save space.


1.Multiple capacity freezers, from 370L to 1,800L, 2.0ml vials storage capacity from 15,600 to 94,500.

2.Excellent temperature uniformity and stability, enabling samples to be stored at -190°C vapor phase environment.

3.Excellent vacuum performance and structural design ensure minimum liquid nitrogen consumption and lower storage costs.

4.Advanced temperature, liquid level monitoring and alarm system, and can realize remote monitoring.

5.Automatic supply of liquid nitrogen, safe and labor-saving. 

6.The liquid nitrogen supply system is controlled by multiple solenoid valves, which can effectively prevent the overflow of liquid nitrogen and sample contamination caused by high LN2 level. 

7.Manual filling available under special circumstances.

8.Compatible with vapor phase and liquid phase storage modes, users can choose according to their needs.

9.The optimized mechanism design realizes high-density storage to save space.

Humanized Design

1.Defog function, easier to find samples and shorten lid opening time.

2.After 48 hours of lid open, temperature in the freezer remains below -150℃ (according to the factory test standard).

3.The remote alarm interface can be connected to the central alarm system.

4.Standard automatic charging backup battery to ensure the normal operation of the system for a period of time after power failure.
