Description

Reaction tube with protection function Technical Field The utility model relates to the technical field of reaction tubes, in particular to a reaction tube with a protection function. Background The freeze-dried microsphere is characterized in that a reagent or a liquid medicine is sprayed into liquid nitrogen through a professional precise micro pump, the liquid nitrogen is quickly frozen into small solid spheres with uniform and regular shapes at extremely short and extremely low temperature, then the small solid spheres are collected and placed into small freeze-drying equipment for freezing and storing, the freeze-dried microsphere is often applied to a reaction tube for sample application, the reaction tube is a test consumable applied in the bacteria culture and identification process in a laboratory, and the characteristic of typical biochemical reaction of bacteria on the consumable is utilized to judge a product of bacterial genus. At present, the freeze-dried microspheres are often stored in a reaction tube, and the inside and the outside of the reaction tube are isolated by a packaging cover so as to protect the freeze-dried microspheres from being polluted, thereby improving the accuracy of laboratory bacteria culture data. The freeze-dried microsphere storage reaction tube is light in weight and extremely low in water content due to the small diameter of the freeze-dried microsphere, static electricity is easily generated, the freeze-dried microsphere is easily adhered to a packaging cover, and the freeze-dried microsphere is easily lost along with the cover when the cover is opened. Disclosure of utility model Based on the above, it is necessary to provide a reaction tube with a protection function against the problems of the prior art that the freeze-dried microspheres are lost along with the cap and the sample is difficult to be added.
