Grant Bio DEN-1 & DEN-1B Densitometers


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 0.5 to 4.0 McFarland units (DEN-1) 0.0 to >7.5 McFarland units (DEN-1B) with a small standard deviation. If required, it can deliver a wider measurement range (up to 15.00 McFarland units), but with a greater standard deviation.

Key Features

  Measurement range: 0.5 to 4.0 McFarland units (DEN-1), 0.0 to >7.5 McFarland units (DEN-1B)
  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 tubes can also be accommodated by using the optional tube adaptor D-16
  Extremely compact design with small footprint and low profile - fits easily into the smallest workspace
  DEN-1b - either battery powered by 3 x AAA or via external power supply
