YDS series liquid nitrogen tanks are mainly used to store liquid nitrogen and biological samples.
Liquid nitrogen tank, also known as "liquid nitrogen biological container", is a low-temperature container that can store liquid nitrogen and biological samples. According to their uses, they can be divided into liquid nitrogen storage tanks, self-pressurized liquid nitrogen tanks, and gas-phase liquid nitrogen tanks. Among them, liquid nitrogen storage tanks can also be subdivided into storage types and transportation types. The storage type is mainly used for static storage and is not suitable for long-distance transportation during work; the transportation type is specially designed to meet transportation conditions and has an internal shock-proof function. Support, while also allowing for static storage when needed.
Since liquid nitrogen tanks are used to store samples, they need to be used correctly:
before use:
1. Check the jar
Check whether the shell has any dents or dents, and whether the vacuum port is intact;
Check whether there are foreign objects or impurities in the tank. If there are foreign objects, they need to be removed to prevent the inner tank from being corroded;
2. Pre-cooling
Inject a small amount of liquid nitrogen into the tank to cool the inner liner;
After injecting liquid nitrogen, cover the neck plug and leave it for a few hours, such as the boiling phenomenon disappears and the liquid nitrogen tends to stabilize;
When the water droplets or frost produced by the heat exchange of the tank body fade away and there is no white frost on the neck plug, it means that the pre-cooling is completed.
when using it:
1.Storage
Store in a well-ventilated and cool place, do not expose to direct sunlight;
Keep upright and do not tilt, lay horizontally, invert, pile up, hit each other or collide with other objects;
2.Transportation
Handle it gently when moving and avoid sudden movements;
It must be fixed during transportation to ensure that it will not shake during transportation;
After use:
Cleaning:
1. After the liquid nitrogen has evaporated, let it sit for several hours until the internal temperature of the container returns to normal temperature.
2. Pour warm water at 40 -50 into the container, and then wipe it with a cloth.
3. Rinse 2-3 times with clean water.
4. Invert the container to dry naturally. You can also use hot air to dry it. The suitable temperature is 40 -50 . Avoid hot air above 60 .
After cleaning, store it in a dry and ventilated place, and check it regularly for next use.

In the laboratory, cell samples need to be placed in liquid nitrogen for cryogenic storage. However, some samples must not only be cryopreserved, but also stored in the gas phase without contact with liquid nitrogen. The former can be solved with a conventional liquid nitrogen tank, and the latter can also be solved with a gas-phase liquid nitrogen tank. However, the capacity of gas phase tanks is relatively large, above 350 liters, and the samples that laboratories need to store in gas phase are not always large. When the quantity is small, using gas phase tanks to store them is really overkill. So how to preserve these samples?
There is a small gas-liquid nitrogen tank, you can also call it a small gas-liquid tank! It is also specially used for gas phase storage of stem cells, embryos, semen and other biological samples. It has moderate capacity, low liquid nitrogen loss, easy operation, and is more suitable for laboratory gas phase storage of small quantities of samples.
Its gas-phase preservation principle is very simple. It is based on the characteristics of liquid nitrogen having a boiling point of -196.56�°C under normal pressure and the natural formation of nitrogen. The area of the small gas-liquid phase liquid nitrogen tank is divided into two, liquid nitrogen is placed at the bottom, and the sample is frozen. The rack is suspended above the liquid nitrogen, and with the help of the natural volatilization of the liquid nitrogen, a low-temperature environment is formed in the container. At this point, is there a familiar and unfamiliar feeling?
That's right, the small gas-liquid phase tank is a smaller version of the YDD series gas-phase liquid nitrogen tank. Except for the difference in material and capacity, the rest of the characteristics are the same. For example: compatible with gas-liquid phase dual-mode storage, intelligent management system, etc.; therefore, the principles between the two are also interoperable!
In short, the small gas-liquid phase tank makes up for the YDD series's demand for small-volume cell storage in terms of capacity. It is a lightweight and energy-saving gas-phase storage liquid nitrogen container specially designed for gas-phase storage of small-capacity cell samples.
Regarding long-term cryopreservation of cells, there are two optional containers, liquid nitrogen tanks and gas-phase liquid nitrogen tanks.
The former is to freeze cells in liquid nitrogen; the latter is to freeze cells in a low-temperature environment generated by liquid nitrogen;
Both of them also rely on liquid nitrogen for cooling, but some people say that using gas-phase liquid nitrogen tanks is safer. Why is this?
In fact, no product can be guaranteed to be perfect. It cannot be said that using gas-phase liquid nitrogen tanks to freeze cells is safer. It can only be said that the safety index is higher than that of conventional liquid nitrogen tanks.
Mainly manifested in three aspects:
1. Storage mode security
The gas-phase storage mode is used to freeze cells, which uses low-temperature nitrogen volatilized by liquid nitrogen for cryopreservation. There is no contact between cells and liquid nitrogen, which can avoid cross-infection of cells during storage and avoid accidental entry of liquid nitrogen into the cryopreservation tube. pipe burst problem;
2. Temperature safety
The temperature inside the gas-phase liquid nitrogen tank is divided into zones. The temperature difference between the upper and lower parts is about 10�°C, which can be said to be very stable. The temperature at the mouth of the tank can be maintained at -190�°C. The lower the temperature, the lower the temperature. No matter where the cells are stored, , the activity will not be "excited" due to large fluctuations in temperature, thereby losing activity.
3. â??Equipmentâ?? security
The gas phase liquid nitrogen tank has a complete intelligent monitoring system.
It can detect temperature, 3 temperature sensors, transmit internal temperature in real time;
It can monitor the liquid level, determine the liquid level height, and can pre-set high/low liquid level alarms;
In addition to these functions, there are also heat exhaust functions, lid opening and defogging functions, alarm and remote alarm functions, event recording, and communication functions. These functions all serve the safety of cells.
This is why the safety index of gas-phase liquid nitrogen tanks is higher than that of conventional liquid nitrogen tanks.
As we all know, the storage modes of liquid nitrogen tanks can be divided into two types according to sample storage requirements: gas phase and liquid phase, that is, soaking in liquid nitrogen and storing in nitrogen. In order to make it easier for users to distinguish between the two, regardless of industry or brand, they are accustomed to using storage modes to identify them. Liquid phase storage is liquid phase liquid nitrogen tanks, and gas phase storage is gas phase liquid nitrogen tanks. This is also their main way of distinguishing themselves!
Of course, there are other differences besides this, letâ??s introduce them one by one.
1. Model differences:
Including capacity size and national standard naming.
The liquid phase liquid nitrogen tank has a capacity range of 1-175 liters and is named YDS. The national standard stipulates that the material is aluminum alloy.
The gas phase liquid nitrogen tank has a capacity range of 350-1800 liters and is named YDD. The material specified by the national standard is stainless steel.
For user use, just select the appropriate model and type based on the number of samples.
2. Mode differences:
Liquid phase liquid nitrogen tank, the sample is immersed in liquid nitrogen;
The gas phase liquid nitrogen tank meets both liquid phase and gas phase modes. There is a liquid nitrogen storage area at the bottom of the tank to provide liquid nitrogen to the sample area. Note: Vapor phase storage also requires supplementing liquid nitrogen.
3. Management differences:
Liquid-phase liquid nitrogen tanks have a wide range of uses and are relatively small in size. Sample classification management relies on buckets and freezing racks. There is no intelligent control and requires manual labor.
Regardless of the size of the gas-phase liquid nitrogen tank, it is equipped with an intelligent control system that can display the internal temperature, perform relevant alarms, and automatically replenish liquid nitrogen.
Biobank Series provide users with automatic, secure and reliable cryogenic liquid nitrogen freezing systems.Tanks are made of high quality stainless steel,Designed and manufactured according to the national standard GB/T14174-2012.Its mouth adopts a partial mouth structure and has a large capacity, which is suitable for long-term static storage of large quantities of biological products, and has the advantages of large storage capacity of biological products, safe and reliable use, and easy operation.
