Countess® Cell Counting Chamber Slides are designed for use with the Countess® Automated Cell Counter. This set includes 100 boxes of slides (50 slides per box) and 2 × 100 mL bottles of trypan blue (0.4%).

Ready to Use For Your Convenience
Countess® Cell Counting Chamber Slides are individually packaged for your convenience. Each slide has two separate, enclosed chambers that can be used to count one sample in duplicate or to count two different samples. Cell counting occurs in a central location of the counting chamber. The volume counted is 0.4 µL, the same as counting four 1-mm2 squares in a standard hemocytometer. After use, Countess® slides can be disposed of with your regular biohazard waste. Unlike a hemocytometer, there is no need to clean Countess® slides before or after use.

The Countess® Automated Cell Counter works in 3 simple steps:
1. Mix 10 µL of sample with 10 µL of trypan blue, and pipet into a disposable Countess® chamber slide.
2. Insert the slide into the instrument.
3. Press the "Count cells" button.

That’s it—get the total cell count, percent viable cells, and average cell size in as little as 30 seconds.
