Cellometer® Automatic Cell Counters - Advantages

Simple & fast
Morphology observation
Small footprint and affordable
No washing and clogging and cross-contamination
No hardware change between large or small cell sizes
One sample, all data produced with the same measurement

Compare to hemacytometer
Compare to particle and fluorescence counters
Compare to other imaging cell counter
