Automated Cell Counters: Open vs. Closed Systems

Manual cell counting is often time-consuming and prone to error, particularly if the researcher is dealing with large numbers of samples. Human perception of cell definition as well as dilution and pipetting errors are common pitfalls in manual cell counting. Although manual counting provides an initially lower start-up cost, the time spent counting the cells, as well as the errors made in the process, can give rise to greater long-term labor-associated costs.
