Abstract

The utility model discloses a device for detecting deflating bacteria, which relates to the technical field of experimental instruments, in particular to a device for detecting deflating bacteria. When whether the air release bacteria exist in the culture medium is determined, the flat bottom test tube is inverted, the culture medium is filled in the small inverted tube, and the open end of the small inverted tube is moved to the bottom of the flat bottom test tube to be abutted against the flat bottom test tube through the combined action of the adjusting component and the clamping ring. The upper and lower positions of the test tube are turned over, the small inverted tube is inverted along with the flat bottom test tube, and the culture medium is added into the test tube. Because the open end of the small pouring tube is sealed by the bottom of the flat-bottom test tube before the culture medium is added into the flat-bottom test tube, the small pouring tube is prevented from generating bubbles easily when the small pouring tube is fed into the test tube. The technical scheme is mainly used for detecting the deflating bacteria, and solves the problem that bubbles are easy to generate in the process of feeding the Du Shixiao pipe into the test tube.
