Description

Technical Field

[0001] The utility model relates to the technical field of colony detection, in particular to a total colony count detector. Background Art

[0002] The total colony count detector is an instrument used to quickly and accurately detect the total number of colonies in a sample. It is based on optical principles and image processing technology. It illuminates the colonies in the sample through a specific light source and uses an image sensor to capture the colony image. Subsequently, the instrument uses advanced image processing algorithms to analyze and process the image, thereby achieving rapid counting and detection of the total number of colonies. However, during the test, the user is required to place the culture dish for culturing colonies in the correct position. This process is prone to large-scale shaking, resulting in uneven distribution of colonies in the culture dish, making the colonies in some areas too dense, while other areas may have fewer colonies. This uneven distribution will cause errors in counting, making the results inaccurate. In addition, shaking may also damage the structure or morphology of the colonies, further affecting the accuracy of the count. Utility Model Content
