We count cells to set up experiments with a consistent number of input cells. We also count cells after the experiment to assess the impact and to express the data accurately. An automated cell counter makes this a quick, painless, reproducible process. This unit was selected because I liked the compact, all-in-one form factor for my small laboratory space.

The Bad

Inaccurate with trypan blue

The Bottom Line

I like that it does not need a separate computer. It counts perfectly fine without trypan blue (just divide the cell count by two) but it has some serious issues with trypan blue counting. The limited and inflexible software is annoying. I would not recommend this unit.
