Abstract
The disclosure discloses an apparatus and a method for microbial cell counting, and belongs to the field of cell counting. In the present application, by converting a traditional automated intermittent counting process into a continuous counting process, the cell sap fixed in a blood cell plate in a traditional counter becomes the cell sap flowing in a microchannel, so as to prolong the cell detection time and distance. The size of the microchannel is slightly greater than the diameter of microbial cells, so as to ensure that the cells flow through the cross section of the microchannel one by one. At the same time, since the diameter of the counterbores communicated by the microchannel is slightly greater than the width of the microchannel, the flow rate of the cell sap slows down when the cell sap flows to the counterbores.
