Artificial intelligence takes cell counting to a higher level

Thermo Fisher Scientific offers two high-performance, automated cell counters designed to help meet the needs of labs for accurate and precise cell counting without the drudgery, wasted time, subjectivity, and variability of manual hemocytometer counting. Developed by expert cell biologists with the aid of artificial intelligence, the Invitrogen Countess 3 and Countess 3 FL instruments are almost a paradox: automated cell counters that think like a cell biologist.

 

Countess 3 Automated Cell Counters help provide highly accurate and precise counts in brightfield and fluorescence mode counts, enabling single cell workflows and nuclei counting, even for challenging cell sample types. Automated features like rapid capture, autosave, and built-in calculators add convenience and time savings. Whether you’ve been counting cells manually or using an early-generation automated counter, the Countess 3 cell counters represent a significant upgrade in counting accuracy and workflow efficiency. Both the Countess 3 and Countess 3 FL Automated Cell Counters are available to help support compliance with 21 CFR Part 11 FDA guidelines and uses a security, audit, and electronic-signature (SAE) software.

Capabilities of automated cell counting

Don’t doubt the cell count

Algorithms developed by cell biologists and refined using artificial intelligence offer the accuracy of hemocytometer counts and the precision of flow cytometer counts—without the expense or training required by flow cytometry.
