Countess™ Cell Counting Chamber Slides

The disposable Countess Cell Counting Chamber Slides offer convenience in automated cell counting for processing multiple cell samples, busy cell culture facilities, and easy disposal of contaminated or hazardous samples. They also eliminate the risk of contamination from residual samples. After use, Countess slides can be disposed of as standard biohazard waste.

The Countess Reusable Slide is a green and cost-efficient alternative to disposable slides for automated cell counting. The reusable slide enables researchers and cell culture facilities to reduce costs and generate less waste per year, making it affordable for labs to automate their cell counts. The reusable slide is cleaned and dried between counts, just as with a hemocytometer.

Each Countess Cell Counting Chamber Slide has two separate, enclosed chambers for counting one sample in duplicate or 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.

The Countess Automated Cell Counter works in three simple steps:

• Mix 10 μL of sample with 10 μL of a cell viability stain or other desired reagent, including ReadyCount™ stains, and pipet into a Countess chamber slide
• Insert the slide into the instrument
• Press 'Count'

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