Cell Health & Quality Control
Meet the Countstar Mira BF. A highly versatile, AI-powered brightfield cell counter engineered to master an uncompromising range of cell types and sizes. 
Versatility Meets Artificial Intelligence
Transform routine cell counting into a source of clear biological insights. The Mira BF combines dynamic optical magnification with advanced AI algorithms to accurately analyze everything from tiny algae to complex organoid digests. It can process up to 5 samples per batch in just 30 seconds each, smoothly enhancing your typical cell counting workflow.
Variable Optics
Switch between 5.0x, 6.6x, and 8.0x zooms to capture cells from 2 to 180 µm.
AI-Powered Precision
Automatically quantify density, viability, and organoid digests. 
Automated Batching
Process 5 samples per batch in 30 seconds using only 20 µL. 
Hemocytometer Ready
Integrate standard consumables for automated, high-precision counting. 
All-In-One Design
Maximize bench space with an integrated touchscreen.
