DEN-1 & DEN-1B Densitometer Grant Instrument

Descriptions

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.

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 18 mm. 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
