Fluidlab R-300

Fluidlab R-300 | Cell Counter & Spectrometer

Combining a full-fledged spectrometer with an automated cell counter, a variety of analyses such as absorbance, scatterlight and time-series measurements, automated cell counting and staining-free viability measurements can be performed. The intuitive handling and precise measurements make the fluidlab R-300 the laboratory instrument of the future.

Cell Counter
  • Label-free viability measurements via holographic microscopy
  • Large FoV for high statistical significance
  • Small sample volume needed (4-20 µl)
  • Full spectral graphs recorded from 375 to 700 nm
  • No maintenance and re-calibration needed
  • Portable and small
  • Technical Data


The fluidlab R-300 uses the label-free technique of digital holographic microscopy (DHM) to analyze cell number and viability directly in the cell culture environment. Contrary to brightfield microscopy, DHM does not use optical lenses but generates so-called ‘holograms’ of the cells, which are analyzed by a computer.
