The Invitrogen™ Countess™ Reusable Slide offers a cost-effective and sustainable alternative to disposable cell counting slides. Designed for use with the Countess II FL, Countess 3, and Countess 3 FL Automated Cell Counters, this slide enables repeated use, significantly reducing laboratory waste and long-term consumable costs.
Each slide features two chambers, allowing researchers to perform duplicate counts on one sample or two different samples. The counted volume is 0.4 μL per chamber, the same as four 1 mm² squares on a traditional hemocytometer—ensuring accuracy and compatibility with familiar protocols.
The Countess Reusable Slide Holder (A48208) is designed to securely hold the reusable slide, maintaining a consistent field of view and count precision. This holder is included with Countess 3 and 3 FL models and is also compatible with the Countess II FL.
