The Grant DEN-1 and DEN-1B 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 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

Applications

Life science – typical applications include determining concentration of cells (bacterial and yeast cells) in the fermentation process, detecting the susceptibility of micro-organisms to antibiotics, identifying micro-organisms with various test systems, and measuring optical density at fixed wavelength.

Servicing Options Available

Have you considered your servicing requirements? Much like a car, scientific instruments may need a bit of care to keep them working reliably and at their most accurate.

The Camlab Service Department have over 60 years experience in scientific instrumentation. We have a number of highly qualified internal and field-based service engineers able to perform a variety of jobs including preventative maintenance servicing and calibration.

Camlab can offer yearly service contracts which include two main types of preventative maintenance/calibration services – the back to base service and an engineer visit to your site. These options are can be offered with differing turn around times depending on the instrument type and your requirements along with loan instruments if available.
