In the field of biological sample cryopreservation, liquid nitrogen and liquid nitrogen tanks are irreplaceable;
Around their use, some accessories have emerged, such as round buckets and freezing racks;
There are also containers and equipment, such as low-pressure liquid nitrogen tanks, also known as liquid nitrogen supply tanks, and liquid nitrogen pumps, trolleys, alarms, etc.!
Among them, accessories can be saved, the cart can be used, the liquid level alarm can be left alone, but fluid replenishment is indispensable, especially in scientific research experiments, or if there is no fixed gas company to come to refill, and the container itself is not easy to move, so more equipment is needed. Low pressure liquid nitrogen tank or liquid nitrogen pump.
What is the difference between them, and which one should I choose for rehydration?
Answer: Low-pressure liquid nitrogen tank or liquid nitrogen pump, which one to choose for rehydration depends on your own needs and usage scenarios!
In terms of rehydration efficiency between them, the low-pressure liquid nitrogen tank is better; but in terms of price, of course the liquid nitrogen pump is more affordable!
Therefore, if you emphasize efficiency and the container is a cell storage liquid nitrogen tank with a diameter of 30-175 liters or 125mm or 216mm, a low-pressure liquid nitrogen tank will be more suitable. It has safe pressure and a high rehydration rate. Achieve the goal quickly.
If your container is less than 30 liters and has a diameter of 50mm, and the requirements for refilling are not particularly strict, choose a liquid nitrogen pump. The foot-operated type can discharge 3-5 liters of liquid per minute, and the mechanical type can discharge 6-8 liters per minute. The working pressure is around 0.05MPa, which is similar to a low-pressure liquid nitrogen tank. They are all rehydration equipment with low safety hazards!
Overview: Low-pressure liquid nitrogen tank or liquid nitrogen pump, which one to choose for replenishment depends entirely on the needs and the conditions of the container itself!
