Cell Viability
The TC20 cell counter uses multifocal plane analysis to assess cell viability. The conventional method of analyzing viability using a single focal plane can lead to inaccurate conclusions because light scattering and the alignment of cells at different heights in a counting chamber can change the appearance of cells — live cells may appear to be dead and vice versa. To determine if cells are viable, the TC20 counter analyzes each cell using images acquired from multiple focal planes during the focusing step.
Minimize Your Sample Preparation
The broad concentration range of the TC20 cell counter eliminates the need to dilute cells prior to counting, reducing the errors associated with sample dilutions that may be necessary when counting cells by other methods. The counting algorithm discriminates and counts individual cells within clusters of up to five cells, providing accurate counts without the need to extensively declump cells prior to loading.
