At present: liquid nitrogen tanks are common low-temperature containers in laboratories and are often used to preserve specimens, samples, cells, etc., which require the constant temperature characteristics of liquid nitrogen tanks. Speaking of which, here comes the question. Many people will ask what size of liquid nitrogen tank should be used in scientific research laboratories? Laboratory liquid nitrogen tanks are generally larger than 30 liters. There are two reasons: 1. Consider capacity The capacity of liquid nitrogen tanks ranges from 2 to 175 liters. Different capacities can store different numbers of samples. The larger the capacity, the more samples can be stored. For laboratories, there are many people who freeze samples, with a wide variety and large quantities. Therefore, it is recommended to choose a jar of more than 30 liters, which can store a variety of samples without the need for frequent refills. 2. Consider caliber There are 6 options for liquid nitrogen tank diameter,50mm,80mm, 125mm, 127mm,210mm,216mm; There are many types and large quantities of samples stored in the laboratory. Freezing racks are often used for matching. If the diameter is too small, it will not fit in. Therefore, it is recommended to use a diameter of 125mm or above. A larger diameter makes it easier to take samples and is used with a freezing box. More samples can be saved. To sum up, liquid nitrogen tanks used in laboratories generally have a capacity of more than 30 liters and a diameter of more than 125mm. But the important thing is to choose based on your actual needs. If you have any needs, please contact KGSQ liquid nitrogen tank:
Currently, the methods of cell preservation are refrigerator and liquid nitrogen. When it comes to long-term storage, liquid nitrogen wins. However, conventional liquid nitrogen tanks need to constantly detect the liquid level, and the cells cannot be stored higher than the liquid nitrogen level, which is not conducive to long-term storage of cells. However, the "stem cell liquid nitrogen tank" that breaks the rules can do it! For long-term storage of large quantities of dry cell samples, it is ideal to use stem cell liquid nitrogen tanks by default. Why? 1. Storage temperature is -150~-196â?? For cells, the more comfortable storage temperature is -150â??~-196â??. Conventional liquid nitrogen tanks only have a temperature option of -196â??. Samples at this temperature are not in danger. The storage temperature of stem cell liquid nitrogen tanks changes with the sample area. The temperature difference in each storage area is 10�°C, which provides more options for cells. You can choose a more suitable temperature for cells to store. 2. Prevent pollution Another important point in cell cryopreservation, stable storage time and how to prevent contamination during storage. To stabilize the storage time, the stem cell liquid nitrogen tank adopts the characteristics of vacuum multi-layer insulation, electronic temperature control and liquid nitrogen dispersion, making the storage tank intelligent cooling and constant temperature process uniform and stable. To prevent storage contamination, you must know that cells become contaminated because they are in direct contact with liquid nitrogen. First, because the cryopreservation tube is not well sealed, liquid nitrogen enters through the gap. After taking out the test tube, there is a temperature difference and pressure difference between the inside and outside. Under the combined action of temperature and pressure, the tube explodes. Second, bacteria will enter the liquid nitrogen tank after it has been used for a period of time. These bacteria are likely to flow into the freezing tube with the liquid nitrogen and contaminate the sample. Stem cell liquid nitrogen tanks can prevent contamination because they can store liquid nitrogen and cells separately, avoiding direct contact between the two. At the same time, they can also use the low-temperature environment formed by the evaporation of liquid nitrogen for storage to avoid pipe explosions and cross-contamination. risk.
In the medical field, cell storage tanks are often used as cryogenic containers to freeze and preserve biological samples such as cells, vaccines, embryos, etc. During use, the physical characteristics of liquid nitrogen cause it to continuously volatilize. Workers need to observe in time to ensure that the temperature and liquid nitrogen in the storage tank are always in a safe range. At this time, the function of real-time monitoring becomes particularly important. Therefore, the manufacturer designed an intelligent liquid level alarm to quickly solve this problem. In addition, it has many additional functions and is more convenient to use. The functions of the intelligent liquid level alarm are: 1. Temperature display: detect and display the temperature of the cell storage tank in real time. 2. Fault alarm: When the sensor is disconnected or the input is open or short-circuited, the instrument automatically emits an audible and visual alarm, the alarm indicator light on the panel lights up, and the buzzer responds. 3. Over-temperature alarm: When the temperature of the measuring point of the liquid nitrogen container is lower than the low temperature set value or higher than the high temperature set value, the instrument automatically issues an audible and visual alarm. 4. Parameter setting function: directly set the high temperature set value, low temperature set value, control temperature value and control hysteresis value through the setting keys on the panel. 5. Silencing function: When the instrument is in the sound alarm state, if necessary, you can click the "Alarm" button to stop the buzzer and eliminate the sound. Click again to turn on the sound. In the setting state, click the "Alarm" button to save the setting value. 6. Power soft switch: Long press the "Power" button on the panel to turn off the instrument power, and long press the "Power" button again to turn on the instrument power. With the blessing of these functions, the intelligent liquid level alarm adds a layer of guarantee to the safety of biological samples.
Stem cells are cells with the ability to self-replicate and differentiate into multiple directions. Under certain conditions, they can differentiate into cells with multiple functions and have the ability to repair various tissue functions and regenerate organs. Therefore, they are also called "universal cells." Such important stem cells can only play a greater role if they are preserved intact. Stem cell storage tanks are a common storage method for preserving stem cells. Using liquid nitrogen to place stem cells in a low-temperature environment can effectively extend the storage time and maintain their vitality and function. Since different users have different amounts of stored stem cells, there are three storage tanks to choose from: 1. For liquid phase storage of hundreds or thousands of stem cells, YDS series aviation aluminum liquid nitrogen tanks can be selected; 2. For gas phase storage of thousands of stem cells, small gas-liquid phase stem cell storage tanks can be used, which are also made of aviation aluminum; 3. If the number of stem cells exceeds 10,000, it is more appropriate to use a gas phase stem cell storage tank. Each of these stem cell storage tanks has its own advantages. Liquid phase storage can maintain a constant temperature of -196�°C, but they lack intelligent management. The small gas-liquid phase storage tank is a mini version of the YDD storage tank. It has the same gas-liquid phase dual mode, intelligent management of samples, automatic replenishment and alarm. In addition, the use of aviation aluminum materials with stronger thermal insulation and lighter weight also combines the advantages of YDS. Therefore, when storing stem cells, you must choose an appropriate storage tank based on the number of cells and storage method.
Simmental cattle are an excellent breed of cattle. Livestock farmers will buy Simmental cattle frozen semen and cross-breed them with local cattle to improve the quality of cattle and gain greater breeding benefits! The purchased frozen beef semen cannot be stored in a normal temperature tank. What kind of tank should be used to store it? â??â??Semen storage tank! After Simmental cattle semen is extracted, it will quickly become inactive at room temperature and cannot be used. However, through the semen storage tank, the semen is specially treated and soaked in liquid nitrogen. The deep low temperature of liquid nitrogen -196�° can be used to preserve sperm for a long time. Activity, wait until use before taking out and thawing. Specific steps for thawing frozen cattle semen for breeding: 1. Lift the bucket to the mouth of the jar and use long tweezers to quickly pinch out the frozen wheat tube; 2. Dissolve the frozen wheat tube in warm water at 30-40�°C, and take it out when it is half melted; 3. Check the sperm activity. If the activity is above 0.3, the breeding success rate is high and it can be used for insemination. 4. Load the semen into the gun and output it as soon as possible. Do not store it for a long time. Notice: Insemination time: The appropriate insemination time is after the cowâ??s estrus period, when the breeding success rate is higher. Storage time of frozen semen at room temperature: After thawing, the longer the frozen semen is stored at room temperature, the lower the activity. Therefore, it should be thawed and infused immediately to avoid long-term storage or repeated freezing.

Urea ammonium nitrate solution, commonly referred to as UAN, is a liquid nitrogen fertilizer which is made up of a mixture of urea, ammonium nitrate and water. Nitrogen fertilizer is responsible for the production of amino acids and proteins and indirectly supports the production of vitamin B. Nitrogen application is the main factor to improve plant growth, development and yield of all crops. Usage: The use of modern crop application methods of UAN are designed to provide very precise application of UAN to the crop. Furthermore, UAN applications can provide better economics for the farmer than dry fertilizer applications because the farmer can add other crop protection products like herbicides, insecticides and fungicides to the UAN and can be applied to the crop in a single application.
