The Grant bio DEN-1 and DEN-1B are a compact benchtop densitometers (suspension turbidity meter) for measuring turbidity of cell suspensions in a variety of life science applications.

The densitometers are designed, and factory calibrated to measure turbidity in the range of McFarland units. For DEN-1 and DEN-1B it is 0.00 to >15.00 McFarland units with a small standard deviation.

  • Measurement range: McFarland units 0.00 to >15.00
  • Measurement time : 1 second
  • Precision: ±3%
  • Readings, conveniently shown in McFarland units, are clearly visible on the bright LED display
  • Factory calibrated - retains calibration without power supply
  • Can be user calibrated with commercial standards or cell suspensions prepared in the laboratory
  • Designed for tubes with an outer diameter of 18mm. 16 mm and 12mm tubes can also be accommodated by using the optional tube adaptor D-16 (included) or A-12 (sold separately)
  • Extremely compact design with small footprint and low profile - fits easily into the smallest workspace
  • DEN-1B - either battery powered by 3 x AA or via external power supply
