In fact, NanoEntek explicitly says that “C-Slide” is the new name for “Countess Slides”!Countess™ Cell Counting Chamber Slides are exclusively bundled for your benefit.

Each slide has two discrete, encased chambers that can be utilized to include one example in the copy or to count two unique examples. Cell including happens in a focal area of the counting chamber.

The volume counted is 0.4 µL, equivalent to including four 1-mm2 squares in a standard hemocytometer. After use, Countess™ slides can be discarded with your ordinary biohazard squander.

Dissimilar to a hemocytometer, there is a compelling reason need to clean Countess™ slides previously or after use. In fact, NanoEntek explicitly says that “C-Slide” is the new name for “Countess Slides”!

In fact, C-Slides are compatible with EVE™ and EVE™ Plus cell counters, also NanoEnTek products!

All these slides are built the same, are prepared in the same way, work with the same automated cell counters, and are disposed of after use. The only difference is the label on the packaging.
