Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation devices, in particular to a culture medium heat preservation device. Background Art

[0002] The microbial limit test method is a method for checking the degree of microbial contamination of non-specified sterilized preparations and their raw materials and excipients. The inspection items include aerobic bacteria count, mold and yeast count and control bacteria inspection. The culture medium is the basis of microbial testing and directly affects the results of microbial testing. The "Chinese Pharmacopoeia" stipulates that the solid culture medium used for microbial limit testing is only allowed to be thawed once after sterilization. The thawed culture medium should be placed in an environment of 45℃~50℃ for no more than 8 hours.

[0003] At present, the commonly used insulation devices in laboratories are water bath insulation and forced air drying oven insulation. The former can easily cause condensed water to drip into the culture medium, causing bacterial contamination or causing the culture medium to float or tip over. The latter is usually placed outside the clean room, making it inconvenient to take the culture medium, and long-term insulation can easily cause the culture medium to lose some water.

[0004] Therefore, it is necessary to develop a culture medium insulation device that is suitable for use in a clean room and is easy to use. Utility Model Content
