Invitrogen™ Countess II Automated Cell Counter by Thermo Fisher Scientific

"We purchased this as a replacement to the original Countess cell counter which we had several years of experience with. This was a seamless transition. We use it for basic cell counting and viability analysis. It is capable of analyzing cell size but we have no need for this feature so I can't comment specifically on that. Overall, it works fine and matches up with our manual counts using a hemocytometer."

"Easy to use, good value, good feedback and comments from several labs in the institute"

"Easy, straight forward reliable results. Much easier to use than other methods we have and has quickly become our go to instrument. Very versatile with numerous options to fit any type of cell or condition."

"With this product, we save a lot of time for cell culture. However, it is a little bit tricky to adjust to the optimal focus. "

"Cell counter Countess II stands out for its ease of use. Its image quality allows us to define easily cells of interest and its software is very precise. Drawbacks are the price and that it needs its own slides for counting that cost a lot."

"Great flexibility to choose the fluorescence filters for your application. Good value because reusable counting slide helps reduce consumable costs. Nice precision auto-focus to improve accuracy and reduce variability. It's simple and easy to use with a touch screen interface."
