The Thermo Fisher Countess II FL is a reliable cell counter and viability platform with the added convenience of optional fluorescence capabilities. The reuseable slide option for this cell counter means cutting down on consumables cost significantly. Having an automated cell counter means eliminating the subjectivity and time sink of manually counting. This automation gives you precise findings and reducing user to user variables, returning results often in as little as 10 seconds. The Thermo Fisher Countess II FL Cell Counter has two optional user changeable fluorescence channels. With these optional fluorescence channels, researchers can utilize EVOS light cubes and customize them to fit their needs. This cell viability counter comes with brightfield and full autofocus to monitor protein expression and measure cell viability before downstream analysis. Users can also assess the apoptosis of cells to measure capase activation and transfected or transduced cells in a population.


With the Countess II FL, researchers can gate their cell count based on cell size, circularity, expression, and brightness for an added degree of refinement. Including or excluding these specifics let users drill down their results to a granular level. Having the two distinct fluorescence channels mean a more accurate reading of complex samples. This cell counter uses these features to save you time and money when it comes to downstream analysis such as flow cytometry or high content analysis. The Countess II FL counts objects between 4 and 60 µm, while cells between 7 and 60 µm can be counted and analyzed for viability. Images and cell count results captured by this cell counter can be saved after each count in a variety of formats. Currently there are no fluorescence blocks offered with this cell counter, however, there are many to choose from direct from Invitrogen so you can customize to your assays and scale up when you need it.
