Customer stories

“Fast count and nice instrument, easy to use!! I love the small counter!”

Dr. Xin Xu, Baylor College of Medicine

“It’s very easy to use and it also allows me to quickly update my lab notebook so that each experiment uses the same number of cells. Quick and efficient.”

Lakeisha Tillery, Meharry Medical College

“It outperformed all other competitors' models that we tried.”

Michael DaCosta, The Jackson Laboratory

“It is very effective at counting cells. It works very well.”

Mairead Bretney, Sanford Burnham Medical Research Institute

“The Countess II makes it very easy to count cells accurately and quickly—the fact that it tells you the dead cell and live cell count is icing on the cake.”

Faryal Mir, MIT

“We compared to a hemocytometer and the Countess II always obtained very close results. The fluorescent measurements are a great tool for us to quantify the % transfection and transduction efficiency in our experiments. The light cubes used to detect fluorescence are very easy to switch out when more than two fluorescence sources are needing to be detected. The automatic focusing is very effective and accurate with the option to manually focus.”

David Waynar, Santa Cruz Biotechnology

“This equipment is very useful for the purposes it is used in our lab. We love it!”

Kristin Harwood, BioMarker Strategies, LLC

“Great for a quick check of transfection/transduction efficiency. Easy to use and seems pretty sensitive.”

Alex Peister, Morehouse College

“Great device. Broad range of cell densities that it can handle. Good at distinguishing clumps and counting cells within clumps.”

Joanne Rzepka, Veterinary Medical Research & Development

“Low maintenance, fast easy accurate cell counts. Easy for students to use and comprehend.”

Robert Dean, D’Youville College

“A very accurate cell counter and you can use it to count fluorescent cells as well. Excellent product. I’m very happy with it. I highly recommend it.”

Massimo Ammirante, University of California, San Diego
