1.The corresponding cryogenic storage tank can not be filled with other cryogenic media, the container can only be filled with the production of customized cryogenic media, so as not to cause an explosion with the container itself on the structure of combustible substances.

2.Tthe container should be placed in a cool, dry place, the room should be well ventilated.

3.Emptying nozzle with repeatable pumping structure, please do not start the user, so as not to affect the performance of the preservation of cold.

4.The general temperature of the cryogenic liquid is -20 to -196 ℃, the operation should be protective measures, such as wearing leather, cotton gloves, etc., hands do not bare. Prevent the splash of cryogenic liquid, touching the skin or eyes caused by frostbite.

5.Cryogenic liquid filling: container filled with low-temperature liquids and re-filling after long-term disuse, because the liner is room temperature, do not fill too fast, should be injected in small amounts, so that the liner gradually cooled, the boiling phenomenon diminished before speeding up the filling rate. Otherwise, it will boil and splash outward, causing frostbite.
