19 Jun 2017 Manual cell counting with a hemocytometer and trypan blue can lead to erroneous results, but in many laboratories, this method is considered to be the standard technique for counting cells. Counting cells with the automated cell counters and image cytometry will help resolve these problems.
The worst results were obtained in manual counts of SF samples kept at room temperature; these samples at 48 hours showed a variation between ?47% to 42% of the initial results. CONCLUSIONS—Automated cell count of the SF offers advantages: it gives higher precision and consumes less time. The stability of the
Before deciding between automated or manual counting, start with defining what cells are to be counted. Only when it is clear what you want to count and in what quantity, you can properly evaluate setups which are available to you. Since the beginning of operations in 2012, we noticed a trend among our partners and
1 Mar 2017 In many laboratories, manual cell counting is considered the standard technique for counting cells but despite this fact, manual cell counting with a hemocytometer and trypan blue can still lead to erroneous results. These problems can be resolved by counting cells with the automated cell counters and
Cell counting is any of various methods for the counting or similar quantification of cells in the life sciences, including medical diagnosis and treatment. It is an important subset of cytometry, with applications in research and clinical practice. For example, the complete blood count can help a physician to determine why a
Introduction. The Cellometer image cytometers are capable of performing automated concentration and viability measurement using both trypan blue and fluorescent methods. The fluorescent instruments such as Auto 2000 and K2 determine viability by counting cells stained with acridine orange (AO) and propidium iodide

It is vital to know the specific cell concentration and viability of a cell sample to obtain reproducibility in subculturing, monitoring growth rates or for cryopreservation1,2. But manual cell counting of the cell concentration can give rise to large errors in cell concentration and viability.
18 Apr 2015 A viable cell count is essential to evaluate the kinetics of cell growth. Since the hemocytometer was first used for counting blood cells, several variants of the methodology have been developed towards reducing the time of analysis and improving accuracy through automation of both sample preparation and
