Countstar Mira BF

Most Versatile Bright-Field Cell Counter

Key Features

  • Multiple magnifications at 5x, 6.6x, 8x
  • AI-powered workflows for cell density, cell viability, organoid digest counting
  • Compatible with hemocytometer
  • 20 µL/sample, 30 sec/sample, 5 samples/batch
  • Compact, all-in-one design

Cell counting of wide range of samples

  • Algae (2-5µm)
  • Yeast (5-10µm)
  • Mammalian cells (>10µm)
  • Organoids/spheroids (up to 100µm)

AI-powered cell count and viability analysis

  • Confident cell identification using AI-powered algorithms (green: live cells; red: dead cells)
  • Accurate detection of single cells in clusters (white circle)
  • Excellent accuracy and high reproducibility (<5% CV)

Automatic cell counting using hemocytometer

  • Compatible with common hemocytometers
  • Faster, more accurate, and better reproducibility than manual counting
