Since traditional blood cell counting plates can no longer meet the needs of high-speed cell research, there are more and more automatic cell counting devices on the market. Commonly divided into two categories: image-based cell counter (Automated vision-based counter) and cell counter based on the Coulter electrical impedance principle. The main difference between the two is that the former scans images in the field of view of the instrument and relies on the set upper and lower limit cell sizes for image recognition, while the latter calculates the number of cells based on the potential changes caused by the cells through the pores (for the Kurt principle, see Here), the two principles are different, so the results obtained are also very different. The following is a comparison of the result accuracy, repeatability, and speed of the counting of various types of cell counters. Readers are advised to purchase a cell counter suitable for your use according to your own needs.
ã€Comparison of accuracy】
Figure 1. Comparison of the counting results of various cell counters with actual values ​​at different cell concentrations
The above figure shows that at high cell density, the counting result of the blood cell counting plate deviates from the actual cell density, while the image-based cell counter has a large deviation at multiple concentrations. This shows that the cell counters based on the Coulter principle (Coulter counter and Scepter cytometer) are superior to the other two cytometers in counting accuracy. (The sample is common COS7 cells)
