BioRad TC20 Cell Counter

Quick Facts

The TC20 automated cell counter counts cells in one simple step using its innovative auto-focus technology and sophisticated cell counting algorithm to produce accurate cell counts in less than 30 seconds.

  • Compatible with a broad range of cell sizes and types — counts cell lines, primary cells, and stem cells
  • Innovative auto-focus technology — removes the variation associated with manual focusing and leads to precise cell counts in 30 seconds
  • Flexible cell size gating — user selects a population of interest in complex samples, such as primary cells, or lets the cell counting algorithm do all the work
  • Accurate cell viability analysis — analyzes cells using multifocal plane analysis
  • Easy to archive and analyze — stores up to 100 counts in the onboard memory for access any time, or use the optional TC20 data analyzer software on your PC to further analyze exported cell images (From BioRad)
  • This resource is free for all BRC users and doesn’t require reservations. Disposable slides are available for a cost of $5 per slide.
