X2 Cell Counter - Cell Count and Imaging Cytometry

Cellometer X2

Optimized for brewing yeast, wine yeast, platelets and other small cells.

The Cellometer X2 utilizes bright field imaging, fluorescent imaging and pattern-recognition software to quickly and accurately identify and count individual cells. Cell count, concentration, diameter, and % viability are automatically calculated and reported.

The Cellometer X2 Image Cytometer is specifically optimized for simple, 1-step determination of yeast concentration and viability. The Cellometer X2 is ideal for research laboratories and small and large breweries looking to automate their fermentation monitoring. Performance of the Cellometer X2 has been proven in the largest breweries in the U.S. and the leading breweries and institutes in Europe.

Bright field images can be viewed to confirm cell morphology. Counted bright field images show counted cells within cell clumps. Fluorescent images show dead cells for confirmation of viability results. Analysis of both bright field and fluorescent images from each sample makes 1-step concentration & viability determination possible.

Not only can those "classic" parameters as count and viability be analysed, the X2 also offers the easy analysis of the vitality (=metabolic activity) or yeast cell cycles.  

And if it isn´t yeast, small cells like platelets and even some bacteria can readily be counted with the X2.
