Countess Automated Cell Counter from Thermo Scientific

The Countess™ automated cell counter uses state-of-the-art optics and image analysis to automate cell counting. The Countess™ automated cell counter is a benchtop counter designed to measure cell count and viability (live, dead, and total cells) accurately and precisely, using the standard trypan blue technique.

Using the same amount of sample that you currently use with the hemocytometer, the Countess™ automated cell counter takes less than a minute per sample for a typical cell count and is compatible with a wide variety of eukaryotic cells and provides information on cell size.

The Countess™ automated cell counter offers an intuitive user interface, and provides the option to save and print cell count data using the Countess™ software (download from www.invitrogen.com/countess) and USB drive supplied with the instrument or available separately.

The Countess™ automated cell counter is supplied with disposable Countess™ cell counting chamber slides that contain two enclosed chambers to hold the sample to allow you to measure two different samples or perform replicates of the same sample. The cell counting occurs in the central location of the counting chamber and the volume counted is 0.4 μL, the same as counting four (1 mm × 1 mm) squares in a standard hemocytometer.
