The liquid nitrogen tank lock cover is mainly designed to protect the storage samples safely, lock the container, and prevent others from opening it casually, so as to protect the sample from safety and anti-theft.
It is composed of two parts, a flip cover and a base, and is locked on the base to facilitate the user to lock. However, it has no effect on the evaporation of liquid nitrogen and the lock cover.
Note: The lock cover does not contain a lock, and the lock requires the user to configure it. The use of a lock cover ensures the safety of the stored sample. Another reason for the lock cover is that it looks more complete and the overall effect is better.
