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.
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.
Set of liquid McFarland standards in 16mm ø glass tubes. 0.5/1.0/2.0/3.0/4.0 can be decanted into an alternative tube (shelf-life no longer valid). Requires D16 adaptor, supplies with DEN-1/DEN-1B
Spare tube adaptor for tubes with 16mm outer diameter
