Dominica-nitrogen freezer-liquid nitrogen container for cell storage
Vapor phase liquid nitrogen freezers are suitable for the cryopreservation of large quantities of biological samples such as stem cells, embryos, vaccines, etc. They are made of low-temperature resistant stainless steel, have large capacity and are easy to operate. They are ideal for large scientific research laboratories and international biological sample banks, providing users with fully automatic, safe and reliable deep-cryogenic liquid nitrogen storage systems.
So, do you know the specific advantages and characteristics of liquid nitrogen freezers?
1. Temperature uniformity and stability: The temperature difference of the entire storage area does not exceed 10°C. During vapor phase storage, the low temperature at the top of the cryopreservation rack can reach -190°C, which ensures the uniformity and stability of the temperature and is conducive to the long-term preservation of samples.
2. Compatible with vapor phase and liquid phase storage modes: Not only does it support vapor phase storage mode, it is also compatible with liquid phase storage mode. Vapor phase storage uses the low-temperature nitrogen evaporated from liquid nitrogen to store samples, avoiding direct contact between samples and liquid nitrogen, thereby avoiding the problem of bursting tubes and cross-infection of samples when the cryopreservation tubes are taken out, and ensuring the safety of sample storage.
3. Large storage space: The volume ranges from 350-1800 liters, which is much larger than ordinary liquid nitrogen tanks and can store more samples at one time. Its unique slanted mouth design and rotating tray partition access increase space utilization and reduce the storage cost of unit samples.
4. Intelligent management system: Equipped with an intelligent monitoring and management system, it can realize functions such as automatic monitoring of the temperature in the tank, abnormal reminders, remote alarms, and automatic replenishment of liquid nitrogen. This system not only improves the convenience of use, but also reduces the cost of manual supervision and ensures the safe storage of samples.
In short, the vapor phase liquid nitrogen tank provides an efficient and safe solution for laboratory research and sample preservation through its unique advantages.
