The Cryogenic Tubes
Description:
Note:
1. The thread of the external thread cap is not directly exposed to the outside, which minimizes the possibility of cross-contamination;
2. The internal thread cap has the same diameter as the cryogenic tube, which has an advantage in intensive storage applications;
3. The maximum volume of the external thread cap is closer to the nominal volume than the internal thread cap. Since the content volume usually increases during liquid freezing,
the recommended usage volume of both external and internal thread cap cryogenic tubes is 80% of the maximum volume;
4. 
Both storage methods are aimed at ensuring the safety of cryogenic storage and can be freely selected according to the users actual needs.
