Vapor Phase Liquid Nitrogen Tank

In biological sample centers or scientific research institutions, there are a large number of cells, strains, vaccines and other samples that need to be cryopreserved. The scientific research of these samples is of great significance, and their safety cannot be ignored. In addition, there are requirements for batch management and data collection. Vapor phase liquid nitrogen tanks are often chosen over aviation aluminum Dewars. Vapor-phase liquid nitrogen tank, also known as "stem cell liquid nitrogen tank", is named after it is often used to establish stem cell banks. It is different from ordinary liquid nitrogen containers. It has two storage modes: gas phase and liquid phase. The sample storage method is unconventional and its working principle is break the usual. Sample storage methods in gas phase liquid nitrogen tanks: Partition management, gas phase preservation! The inner tank of the stem cell liquid nitrogen tank is divided into two areas. The upper area is for samples, which is the storage area for stem cells, embryos, bacteria, etc.; the lower area is for liquid nitrogen storage only and does not contain any samples. The bottom position, which is the liquid nitrogen storage area, is equipped with an evaporator to provide evaporated nitrogen for sample storage to cool down. The sample is only "close" to the liquid nitrogen, but does not touch it, and the volatilized low-temperature nitrogen is used to store the cells. Working principle of gas phase liquid nitrogen tank: The principle is actually very simple, such as the use of liquid nitrogen evaporation cooling mentioned above! When the nitrogen in the sample storage area is insufficient to support the sample demand, the bottom evaporator starts working to supply liquid nitrogen to the upper part. This has the advantage of avoiding sample cross-contamination. The reason why I donâ??t mention its other storage mode - liquid phase is because the liquid nitrogen reserve in the container is large, much higher than that of conventional liquid nitrogen containers, and the evaporation loss of stainless steel is higher than that of aluminum alloy. When storing in liquid phase, replenish the liquid. Frequent and troublesome, difficult to use, only gas phase storage is recommended. In addition, the gas-phase liquid nitrogen tank also has high dual-gallery vacuum + high thermal insulation performance, which reduces heat conduction, reduces the evaporation rate of liquid nitrogen, and maintains stable pressure inside the tank. The built-in intelligent control management system is used for real-time detection and abnormal warning of temperature, pressure and liquid level to ensure the stability of the tank and the safety of stem cells.

The vapor phase liquid nitrogen tank is a device used for low-temperature storage of experimental samples such as stem cells, plasma, semen, embryos, various tissues and organs. It can accommodate large quantities of biological samples for long-term static storage, and has both liquid and gas phase storage methods. Compared with traditional liquid nitrogen containers, it is more powerful. Let's talk about the advantages and characteristics of the vapor phase liquid nitrogen freezer in detail. 1. Intelligent supervision: equipped with an intelligent monitoring and management system, it can realize automatic monitoring of the temperature in the tank, abnormal reminders, remote alarms, event recording and automatic rehydration, saving time and effort, safe and reliable. 2. High-density storage: large volume, usually between 350-1800 liters, with higher space utilization, can store a large number of samples. 3. Dual storage mode: provides two modes of liquid phase storage and gas phase storage. The gas phase storage mode uses low-temperature nitrogen evaporated from liquid nitrogen to store samples, avoiding the possible bursting of the cryopreservation tube when it is taken out, and the problem of cross-infection of samples. â?? 4. Stable opening temperature: The unique large-caliber slanted mouth design can reduce liquid nitrogen loss when opening the lid and maintain the stability of internal temperature changes. â?? 5. Temperature monitoring system: The monitoring system can display the temperature inside the tank in real time with high accuracy, and users can set alarm points by themselves. The above are the advantages of stem cell liquid nitrogen tanks, making it an ideal choice for biological sample storage, ensuring the safety of samples and the effectiveness of long-term preservation.

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. â?? 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. â?? 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. â??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.
