Description

Technical Field

[0001] The present application relates to the field of water bath pots, and in particular to a water bath device with a lifting mechanism. Background Art

[0002] Bacteria are a type of microbial organism that is widely present in every corner of nature, including water, soil, air, human body, etc. For the separation and identification of bacteria, extracting their DNA is a necessary step. Bacterial nucleic acid extraction refers to the process of separating and purifying DNA from bacterial samples. Chemical or physical methods are usually used to destroy the bacterial cell wall and membrane, release the nucleic acid in the bacterial cell and remove other impurities. There are two methods for extracting bacterial nucleic acid: physical and chemical. The physical method mainly destroys the cell wall and membrane through mechanical crushing or physical factors such as high temperature and high pressure to release the DNA in the cell. Among them, the most commonly used physical method is high-speed centrifugation, that is, centrifuging the bacterial culture, removing the cell supernatant, suspending the bacteria with a solution such as physiological saline, adding protease, SDS and other reagents to rupture the bacteria and release DNA, and then purifying and extracting it through centrifugation, washing and other steps. The rupture of the bacteria by protease usually needs to be carried out at a specific temperature to activate the protease, so a water bath is usually used to heat the protease and bacteria at a constant temperature.
