The DEN-1B is a compact benchtop densitometer (suspension turbidity meter) for measuring turbidity of cell suspensions in a variety of life science applications.
The densitometer is designed and factory calibrated to measure turbidity in the range of 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: 0.0 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
ApplicationsLife 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.
