The invention discloses an improved cotton-thread quick-frozen tube convenient to use. The improved cotton-thread quick-frozen tube comprises a quick-frozen tube body, a quick-frozen tube cap and a cotton thread, wherein a plurality of holes are formed in the edge of the quick-frozen tube cap; the cotton thread successively penetrates through the holes in the edge of the quick-frozen tube cap to form a cotton-thread ring; a cotton stayguy is fastened on the cotton-thread ring or the cotton thread on the cotton-thread ring is loose to form a suspension loop pulling head on the cotton-thread ring. According to the invention, freeze tube samples requiring liquid nitrogen quick freezing can be put into or taken out conveniently, quickly and safely, and unnecessary liquid nitrogen loss can be further avoided.
Description
Technical field: [0001] The invention belongs to the field of biological instruments, and in particular relates to an improved cotton thread quick-freezing tube which is convenient to use. Background technique: [0002] At present, when cells need to be frozen, the existing method is to take out an appropriate amount of liquid nitrogen from the liquid nitrogen tank, put the cryovial containing the cells in liquid nitrogen for quick freezing, and then pour the liquid nitrogen back. This operation is cumbersome, and it is easy to be scalded if it is not used carefully, and the loss of liquid nitrogen is also great. Invention content: [0003] The purpose of the present invention is to provide an improved cotton thread quick-freezing tube which is quick and safe to operate and avoids unnecessary loss of liquid nitrogen. [0004] The present invention is implemented through the following technical solutions: [0005] The improved cotton thread quick-freezing tube which is ea...
