Cell Counting Devices Uses Flow To Pass Cells Through A Laser Beam
One type of automated cell counter is the hemocytometer. This device is a specialized microscope slide with a grid pattern etched on its surface. A small sample of cells is placed on the grid and the number of cells in the grid squares is counted manually. The hemocytometer is considered the gold standard for cell counting, but it is time-consuming, and the accuracy of the results is dependent on the skill of the person counting the cells.
Another type of automated cell counter is the flow cytometer. Cell Counting Devices uses flow to pass cells through a laser beam, which allows for the measurement of various characteristics of the cells, such as size, shape, and fluorescence. Flow cytometers are commonly used for cell sorting, but they can also be used for counting cells. The advantage of flow cytometry is that it can provide detailed information about cell populations and can be used to sort cells. However, flow cytometry is a complex technique that requires specialized training and can be expensive.
