Countstar Mira FL

Smart Fluorescence Cell Counter

Key Features

  • Dual fluorescence channels
  • Multiple magnifications (BF: 5x, 6.6x, 8x; FL: 5x)
  • Broad range of AI-powered applications
    • Cell density and viability via Trypan Blue or AO/PI
    • GFP/RFP transfection efficiency
    • Organoid counting and viability
  • 20 µL/sample, 30 sec/sample, 5 samples/batch
  • Compact, all-in-one design.

Cell density and viability analysis using AO/PI

  • Accurate cell identification and characterization by combining bright-field images and fluorescent images (green: live cells; red: dead cells)
  • Confident cell identification in complex samples with wide cell size and shape distribution
  • Accurate detection of single cells in clusters (white circle)

Cell density and viability analysis using Trypan Blue

  • Confident cell identification in complex samples with wide cell size or shape distribution (green: live cells; red: dead cells).
  • Accurate detection of single cells in clusters. (white circle)
  • Detection of smaller cells (T cells, yeast) at higher magnifications (6.6x, 8.0x)

Excellent accuracy and reproducibility

  • Accurate measurements spanning two orders of magnitude
  • CV < 5%

Transfection efficiency assay

  • Sensitive detection of GFP/RFP signals
  • Results comparable to a flow cytometer in a fraction of the time
