Umbilical cord blood is the blood that remains in the placenta and umbilical cord after the fetus is delivered and the umbilical cord is ligated and severed. It contains stem cells that can rebuild the human hematopoietic and immune systems. It can be used for hematopoietic stem cell transplantation to treat a variety of diseases, including hematological malignancies, respiratory diseases, Cardiovascular disease, endocrinology, etc. Currently, umbilical cord blood has become an important source of hematopoietic stem cells.

However, this kind of component obtained from the human body will rapidly divide and proliferate to complete all life activities after leaving the human body, and then die. It is of high value but difficult to preserve. If you are not careful, it will cause direct economic and research losses, unless it is placed in -130 In an environment around ℃.

The implementer of this environment is the liquid nitrogen container tank!

Therefore, you will find that when there are a large number of stem cell samples that need to be preserved, whether it is the founder of the cell bank, the manager of the hospital blood bank, or the personnel of the preservation center, they all choose a specialized cell storage tank - a gas-phase liquid nitrogen freezer, this popular branch of liquid nitrogen container tanks!

Because it has the advantages of large capacity, small daily evaporation loss of liquid nitrogen, safe and reliable use, and easy operation. In addition to stem cells, it is also suitable for the long-term static storage of various tissues and organs such as plasma, semen, and embryos. Originally made for the storage of plasma and stem cells, it has been widely recognized and favored by blood stations, cord blood banks, sperm banks and other institutions since its launch.

What are the advantages of using a gas-phase liquid nitrogen freezer to preserve stem cells?

1. The tank body is made of high-quality stainless steel, with polished surface, good load-bearing, low temperature resistance and corrosion resistance;

2. The tank mouth is designed with an offset structure, large capacity, high vacuum, and low liquid nitrogen loss;

3. Two storage methods, gas phase and liquid phase, can maintain a low temperature environment of -190° on the top of the jar;

4. Rotating trays are used internally for partitioned storage, making it easier to take out cells;

5. It has an intelligent monitoring system and can modify parameters in the settings according to needs;

6. The system can display high and low liquid levels in real time. Ultra-high and ultra-low will provide liquid level alarms, over-temperature alarms, and automatic control of fluid replenishment;

7. It has a hot gas bypass leakage function in the pipeline. The hot gas in the pipeline will not enter the tank during liquid replenishment, ensuring a low-temperature storage environment to the greatest extent;

8. It has a cover-opening and defogging function, which makes it easy to see the stored items and make them easy to extract;
