Description

Technical Field

[0001] The utility model relates to the technical field of bacterial culture, in particular to a storage device for bacterial culture solution for laboratory use. Background Technique

[0002] The culture solution is a nutrient medium containing organic and inorganic components, which provides the nutrients required for the growth and reproduction of bacteria, fungi, algae and other microorganisms. The storage and management of the culture solution helps to protect the purity of microorganisms, maintain the growth and preservation of bacteria, and provide support for subsequent experiments and research. The existing storage devices for bacterial culture solution are composed of a test tube rack, test tubes and sealing plugs. The bacterial culture solution is stored in the test tubes, and then the test tubes are sealed with the sealing plugs to prevent the culture solution from being contaminated. After being sealed, they are placed on the test tube rack.

[0003] Most bacterial culture solutions are stored in test tubes. However, most of the existing storage devices for placing test tubes are integrally formed. When placing test tubes, they cannot be adjusted according to the actual length of the test tubes. Even if a few can adjust the height of the storage rack, the overall height of the placement rack is synchronously adjusted during the adjustment. When placing test tubes of different lengths, there will still be a situation where some shorter test tubes are placed unstably and shake, affecting the stability of the liquid inside the test tubes.
