As we all know, liquid nitrogen is a low-temperature liquid and is volatile. Laboratories usually use the low temperature of liquid nitrogen to preserve experimental samples. The use of liquid nitrogen tanks can effectively reduce the volatilization of liquid nitrogen, but over time during use, the liquid nitrogen gradually decreases.

If cell samples are stored below the level of liquid nitrogen or within the gas phase far away from the tank mouth, it is safe for the samples not to be affected by temperature fluctuations. However, when the liquid nitrogen is less than 1/3 of the total amount, the vaporization time of the liquid nitrogen will increase, and the temperature at the top of the liquid nitrogen tank will rise rapidly as the lid is opened, putting cell activity at risk. During this period, if the liquid nitrogen is not replenished in time, or if the liquid nitrogen is completely evaporated before being replenished, and the temperature of the liquid nitrogen tank rises to normal temperature, the cell samples will not only be damaged, but will most likely die!

In order to avoid such problems, laboratory users often use YDD cell bank liquid nitrogen tanks, also known as stem cell liquid nitrogen tanks, to preserve cells and freeze semen samples.

The YDD stem cell liquid nitrogen tank itself has an intelligent monitoring and management system. Its functions cover liquid level monitoring. In addition to displaying the liquid level in real time, when the liquid level is lower or higher than the set value, an audible and visual warning will be issued, accompanied by a text message. Send and never miss a message, even remotely. If liquid nitrogen is not added in time, this function is triggered and the manager will receive relevant prompts. Samples will not be affected for a short period of time.

In addition, the YDD stem cell liquid nitrogen tank supports two storage modes: gas phase and liquid phase. When using the gas phase mode to store biological samples, the bottom liquid nitrogen volatilizes into nitrogen gas and then supplies the top sample. Liquid nitrogen is not directly related to the sample, and liquid nitrogen cannot soak the sample. , the sample may be damaged.

However, in order to ensure the safety of cell samples, it is recommended that you regularly observe the use of liquid nitrogen and refill the jar with liquid nitrogen in time!
