Countstar – Automated yeast counter

The Aber Countstar is the first slide-based image analysis instrument for yeast cells that can be used with the same safe, traditional stains used in microscopy.

The instrument uses disposable slides containing 5 sample chambers that require just 20µl for each sample.

Using auto-focusing cell image analysis, one measurement takes less than 20 seconds with a 5 megapixel industrial colour camera to provide the cell count (total, live and dead), the viability%, cell diameter and the
degree of aggregation.
