Cell Counters

Cell counters are indispensable instruments in any modern biological laboratory, enabling the rapid and accurate quantification of cells in suspension. From basic cell culture maintenance to advanced applications like immunotherapy development and high-throughput screening, cell counters enhance reproducibility and reduce human error—making them a vital tool in research, diagnostics, and manufacturing environments. Traditional manual counting using a hemocytometer is time-consuming, subjective, and prone to variability between users. Automated cell counters solve these problems by providing consistent, high-speed analysis of cell number and viability. Many models employ image-based analysis or electrical impedance (Coulter principle), and often incorporate trypan blue or fluorescence staining to distinguish between live and dead cells. This ensures reliable results essential for applications like viability assays, cryopreservation, and therapeutic dose preparation. Researchers across oncology, stem cell research, regenerative medicine, and vaccine development rely on accurate cell counts for workflows such as transfection, drug screening, flow cytometry setup, and cell expansion in bioreactors. Cell counters also support critical manufacturing stages in CAR-T cell therapy and other cell-based treatments where dosing precision is paramount. At Wasteless Bio, we offer a wide range of pre-owned and surplus automated cell counters from trusted suppliers, helping labs save money while promoting sustainable research practices. Each listing includes detailed specifications—such as detection method, sample throughput, supported cell sizes, and software capabilities—allowing scientists to make informed purchasing decisions. Choosing Wasteless Bio enables laboratories to maintain high standards of quality and reproducibility while reducing environmental impact and supporting a circular lab economy.
