In laboratories, most commonly used liquid nitrogen tanks have large capacity, large diameter, and weight. If you want to transfer it, it is difficult to carry it with bare hands, and there is still a certain degree of danger. And there is no guarantee that bumps or accidents will not occur during the transfer process. If something goes wrong during the transfer, you'll lose more than you gain.
So how to safely transfer laboratory liquid nitrogen tanks indoors.
You can choose a liquid nitrogen tank trolley, which is a labor-saving and safe transfer equipment.
The liquid nitrogen tank trolley is made of stainless steel, has a large table design, and is equipped with 4 high-load capacity swivel casters at the bottom, which is wear-resistant and low-noise. It has the advantages of convenient installation, labor-saving transportation and strong load-bearing capacity. Put the liquid nitrogen tank on the trolley, which can help the experimenter easily move it anywhere without much manpower. This kind of trolley is not only suitable for laboratories, but can be easily maneuvered and moved flexibly in various complex environments such as hospitals, scientific research institutes or health industries.
However, the trolley also has a range of use. It has different models to choose from. The capacity is suitable for large-capacity laboratory liquid nitrogen tanks from 30L to 190L. Indoor transfers are more portable and greatly improve work efficiency.
The emergence of liquid nitrogen tank trolleys solves the problem of difficulty in transferring liquid nitrogen tanks in the laboratory, which is both safe and efficient.
The liquid nitrogen tank is a low-temperature container that can only store liquid nitrogen and cannot store other liquids. It is mainly composed of inner and outer gallbladders, neck tubes, neck plugs, and buckets. They play different functions in different positions. So what functions does our liquid nitrogen tank neck plug have? What will happen if we accidentally forget to cover the neck plug during operation? You should know that the neck plug is made of polyurethane foam and is used to block the neck of the liquid nitrogen container to reduce the evaporation of liquid nitrogen and play a role in preserving liquid nitrogen. It is light and pressure-free, not easy to break, does not fall off, and can also fix the bucket without adsorbing liquid nitrogen. If you forget to cover the neck plug during use,there will be three situations,the third situation is dangerous. 1. Liquid nitrogen volatilizes in large quantities Liquid nitrogen is a low-temperature liquid that is easily volatile at -196�°C.It will evaporate more quickly when exposed to heat. The liquid nitrogen tank is designed to better isolate heat,so that liquid nitrogen can be stored for a long time.The neck plug is made of polyurethane foam, which is not easy to break and has good thermal insulation properties and can isolate most of the heat. If you forget to cover the neck plug,hot air will enter through the mouth of the tank and accelerate the evaporation of liquid nitrogen.If there are samples stored in the tank,the safety of the samples will be affected and the samples may become inactive. Therefore,when we find that we have forgotten to cover the neck plug,we must first measure the height of the liquid nitrogen in the tank,refill it,and then cover the neck plug. 2. Liquid nitrogen will be contaminated Another function of the neck plug is to prevent impurities or bacteria from falling into the tank. If you forget to cover the neck plug, bacteria and impurities will inevitably fall into the liquid nitrogen tank and contaminate the liquid nitrogen and stored biological samples. 3. Decreased indoor oxygen content Usually, liquid nitrogen tanks are placed indoors. Liquid nitrogen will volatilize more quickly when heated. If the room is not well ventilated, the nitrogen content in the air will increase and the oxygen content will decrease, which may cause the risk of "suffocation". Therefore, Liquid nitrogen tanks stored indoors must be well ventilated. If you have any needs, please contact KGSQ liquid nitrogen tank:
The self-pressurizing liquid nitrogen tank is an efficient and safe liquid nitrogen storage equipment, which is widely used in life sciences, medical research and other fields. So, what exactly is it? First, we need to understand how a self-pressurizing liquid nitrogen tank works. It vaporizes a small amount of liquid nitrogen in the tank, causing the internal pressure of the entire container to increase. When the pressure inside the container reaches the critical pressure, the drain valve needs to be opened to realize the continuous drain function. It is specially used to replenish liquid nitrogen in laboratory cryogenic containers to ensure the smooth progress of experiments. Secondly, the safety of self-pressurizing liquid nitrogen tanks is also very high. It is equipped with double safety automatic control valves, which have double safety measures and are safer to use. It ensures that the liquid nitrogen tank pressure does not exceed the limit, thus avoiding the risk of accidental leakage and explosion. In addition, self-pressurizing liquid nitrogen tanks also have certain sealing properties. Although it looks like a tightly sealed jar from the outside! But it has a vent, a pipe for nitrogen to be discharged. When it is filled with liquid nitrogen, we only need to open the drain valve of the tank, and the nitrogen evaporated by the liquid nitrogen will be discharged to the outside from the drain port. There is no pressure inside the tank. Finally, self-pressurizing liquid nitrogen tanks are easy to operate. It has only 4 valve controls, and users can realize the functions of pressurizing, depressurizing and releasing liquid nitrogen with simple operations. In short, the self-pressurizing liquid nitrogen tank is a highly functional, safe and efficient liquid nitrogen storage device that is widely used in scientific research, medical and agricultural fields.
In laboratories and scientific research institutes, experimental samples and cells often need to be stored in a low-temperature environment for a long time. There are many cryogenic containers on the market, and laboratory liquid nitrogen tanks stand out and are entrusted with reuse. This is because the laboratory liquid nitrogen tank has such advantages. It is made of aviation aluminum, which has strong hardness, light weight, long-term durability and no deformation; large-diameter design facilitates sample pickup and placement; large capacity, stable and safe storage of samples; multi-layer insulation Vacuum design effectively reduces the volatilization of liquid nitrogen; it can meet the different needs of different workers. Although, there are ways to use laboratory liquid nitrogen tanks. 1. Before use It should be placed in a well-ventilated room, away from fire sources, electrical equipment, moisture-proof, and shaded; Avoid storing in places where the temperature is too high or too low, and the humidity is too high or too low; Check the sealing of the liquid nitrogen tank to see if there is air leakage. If there is any abnormality, contact after-sales service in time; 2. When using Use caution when adding liquid nitrogen. New jars should be filled slowly and pre-cooled to prevent the liner from cooling too quickly and reducing its service life; When filling liquid nitrogen, do not pour liquid nitrogen on the vacuum exhaust port to avoid a decrease in vacuum degree; The neck plug is made of thermal insulation material, which can not only prevent the evaporation of liquid nitrogen, but also play a role in fixing the lifting cylinder; Check frequently. If frost is found on the surface of the tank, stop using it; 3.After use Liquid nitrogen tanks should be placed on a stable and flat ground, away from direct sunlight and high temperature environments; When not in use for a long time, it should be cleaned and stored to prevent sample residue from corroding the tank wall and affecting the service life; It is recommended to place it in a well-ventilated area and regularly check the insulation performance of the tank; In short, the role of liquid nitrogen tanks in the laboratory is irreplaceable, but their correct use is crucial. During the operation, you must not only pay attention to the storage of the liquid nitrogen tank, but also the addition and correct use of liquid nitrogen to ensure the safety of staff and samples.
Frozen embryos are one of the prerequisites for implementation, the other is the cultivation of embryos. After the eggs and sperm are completely extracted, in order to ensure the viability of the eggs and sperm, they will immediately enter the cryopreservation stage, suspend their life activities, and then complete insemination in an external culture system to complete the embryo development. After the embryo is transplanted into the uterus, it still needs to be stored at low temperature. The method of preservation is to put it into a low-temperature medium - liquid nitrogen. Since the temperature of liquid nitrogen is much lower than normal temperature, organisms in direct contact will be frozen. Otherwise, the plastic will be frozen brittle. In order to ensure the vitality of the sperm and egg "combination" embryo, a special liquid nitrogen container is needed to store it. We can also call it an embryo storage tank, because it is used for embryo storage at this time. The embryo storage tank is composed of two layers: an inner and outer bladder. The inner and outer layers are insulated by a vacuum. It has good thermal insulation and can reduce liquid nitrogen consumption. Even so, the liquid nitrogen balance and temperature in the tank need to be tested every day to ensure that the ambient temperature of the cryopreserved embryos is normal and stable. In order to ensure the safety of the embryos and improve work efficiency, we can install a liquid level alarm, which can detect the liquid level in the tank. When the ambient temperature reaches the upper and lower limits, an alarm will sound to remind the staff to replenish liquid nitrogen in time. It also supports text messages. , telephone, and email alarm functions. The addition of a liquid level alarm can avoid embryo loss caused by insufficient liquid nitrogen. This safety measure ensures the safety of the embryonic baby to a certain extent, preventing the embryonic baby from being harmed by the external environment and receiving the same careful care as in the mother's body. It not only improves the success rate of IVF, but also improves the efficiency of laboratory work management. Moreover, using embryo storage tanks to freeze embryos ensures their vitality during the period between the completion of cultivation and delivery to the mother, reducing damage to the embryos due to temperature changes, etc., and ensuring the success rate of IVF.
