Overview
The Countess
™
automated cell counter performs viability and cell
counting measurements using the trypan blue method of dead-cell
staining combined with advanced image analysis.
Cell sample is mixed with trypan blue and loaded into a Countess
™
cell counting chamber slide. The camera acquires cell images from
the sample on the slide and the image analysis software
automatically analyzes acquired cell images, and measures cell
count and viability using the trypan blue stain.
A single, sample measurement within a minute provides the
following data:
 Live and dead cell concentration/mL
 Total cell concentration/mL
 Viability (% live cells to total cells)
 Mean diameter
 Cell images
 Graphical data representation
