Cell Counter determine the concentration and viability of cells in a suspension, replacing manual hemocytometer counts that are slow and prone to operator variation. Automated image analysis or impedance detection counts red blood cells, white blood cells, platelets and cultured cells within seconds. Trypan blue and fluorescent staining distinguish live from dead cells, while size and granularity data help separate cell populations and debris. Results are stored with sample identifiers to support traceability and reporting. Typical uses include cell culture passaging, stem cell and cancer research, bioprocess monitoring, blood banking and clinical hematology workflows.
