They can be found in food, cosmetics, feed, and the environment, all within human reach. Contamination by certain microorganisms not only affects product quality but, more seriously, endangers the health and safety of consumers. Biochemical identification tubes for microbial testing are laboratory tools used for microbial identification. They typically contain specific biochemical reaction components and use color changes or precipitation produced by bacterial metabolic activity to determine the biochemical characteristics of bacteria, thereby assisting in the identification of bacterial species. These identification tubes can be used in areas such as food safety, clinical diagnosis, and environmental monitoring to quickly and accurately identify microorganisms.
[0003] When using existing biochemical identification tubes for microbial testing, when it is necessary to heat the biochemical identification tubes for microbial testing in a water bath, the biochemical identification tubes for microbial testing are usually placed in hot water and the hot water is kept warm and heated. In this way, if the hot water evaporates and the water level drops during heating, the operator fails to discover it in time, which will affect the experimental results and lead to inaccurate experimental results. For this reason, we propose a biochemical identification tube for microbial testing. Utility Model Content
