The Countess II FL features a cell sample range of 1 × 10 4 –1 × 107 and processing time in as little as 10 seconds. The featured digital display shows images of cells and sample data making interpretation convenient and easy. The USB port allows users to save cell count results and images and then transfer them to a PC. The compact design allows for this versatile machine to fit easily into any lab environment. The Countess II FL Cell Counter can accomplish all of the functions that the Countess II Cell Counter is capable of, however adds on some additional features. The Countess II FL can count cells from either disposable Countess Cell Counting Chamber Slides or from glass Countess II FL Reusable Chamber Slides. In addition to the brightfield channel, the Countess II FL can accommodate two interchangeable EVOS fluorescent or specialty light cubes, enabling it to be used for multiple-fluorescence research applications. When equipped with EVOS light cubes, this unit can be used to perform assays for cells in suspension, including simultaneous counts of cells stained with two different fluorescent dyes, GFP and RFP expression, apoptosis, cell viability, and cell cycle assays.
