Description

Technical Field

[0001] This utility model relates to the field of culture medium bottle technology, specifically a culture medium bottle for preparing Columbia blood agar plates. Background Technology

[0002] Culture media bottles are commonly used laboratory containers in the fields of biology, medicine, and chemistry for storing and transporting serum, cell culture media, culture media, etc. The main components of Columbia blood agar plates include peptone, beef extract, yeast extract, soluble starch, sodium chloride, agar, and sterile defibrinated sheep blood. These components are precisely formulated, autoclaved, and a measured amount of animal blood is added at the filling temperature before being poured into disposable plastic plates.

[0003] When preparing Columbia blood agar plates, the culture medium solution stored in the culture medium bottle needs to be dispensed into petri dishes. Currently, the culture medium bottles for Columbia blood agar plates are usually filled manually by pouring the culture medium solution from the bottle into the petri dishes. This method cannot measure the quantity of culture medium, resulting in different amounts of culture medium solution in each petri dish. This may lead to differences in the growth conditions of microorganisms in different petri dishes, thus affecting the accuracy and consistency of experimental results. Utility Model Content
