Automated cell counter comparison table

 

While the Countess II/II FL models are no longer available, the Countess 3/3 FL boasts a myriad of enhanced features designed to help streamline cell counting processes with exceptional accuracy and precision.  Explore the detailed comparison between Countess II/II FL and Countess 3/3 FL Automated cell counters below.

 


Which Countess 3 automated cell counter is best for you?

Both Countess 3 models work the same way and share common features

  • Accurate and precise
  • Fast
  • Simple
  • 21 CFR Part 11 compliance support software 
  • Automated
  • Applications beyond counting
  • Reusable slide compatible

Both models accurately count “difficult” samples such as those containing clumpy cells or debris, and both reduce variability between users, helping increase reproducibility.

 

The key difference between the models is that the Countess 3 instrument counts in brightfield mode only, while the Countess 3 FL instrument can count in either brightfield only or brightfield and fluorescence mode using interchangeable EVOS LED light cubes. Fluorescence capabilities open up additional application options for the Countess 3 FL instrument, and can extend your research beyond just GFP and RFP with 14 EVOS LED light cubes to choose from.
