Description

Technical Field

[0002] Microorganisms include bacteria, viruses, fungi, and some small protozoa, microscopic algae, etc. They are small in size and closely related to humans. They cover many types of beneficial and harmful organisms and are widely involved in many fields such as food, medicine, industry and agriculture, environmental protection, and sports. Microbial sampling refers to the evaluation of air from a controlled or uncontrolled environment to determine the number of bacteria and fungal microorganisms it may contain. When preserving the sampled microorganisms, a microbial sampling preservation device is required. In the existing preservation device, glass bottles are usually used to preserve the sampled microbial samples during the preservation process. Due to the different preservation conditions and types of different microorganisms, the samples stored in glass bottles are poorly isolated from each other, and cross-contamination is prone to occur when opening and closing the bottle cap for storage. At the same time, frequent opening of the bottle cap to preserve the sample can easily cause air and other pollutants to enter the bottle, resulting in sample contamination and affecting the preservation quality of the sample. Therefore, we propose a microbial sampling preservation device to solve the above-mentioned problems. Utility Model Content
