Densitometers – McFarland DEN-1 & DEN-1B (Biosan)

Densitometers – McFarland DEN-1 & DEN-1B (Biosan)

McFarland DEN-1 and DEN-1B Densitometers
McFarland Densitometers (suspension turbidity detectors) are used for the measurement of cell concentration (bacterial, yeast cells) during fermentation process, determination of microorganism sensitivity to antibiotics, microorganism identification using various test-systems, for measurement of absorption at the definite wavelength, as well as for quantitative estimation of concentration of colour solution, absorbing green light. Two versions of the product are available:
  1. DEN-1 powered from external energy supply; and
  2. DEN-1B powered both from external energy supply and from batteries (АА). DEN-1B operates with higher precision of measurements (up to 0,01 McF).
The DEN-1 Densitometer is designed for measurement of cell suspension's turbidity in the range of 0.3–5.0 McFarland units (100×106 – 150×107 cells/ml). The DEN-1B Densitometer is designed for measurement of cell suspension's turbidity in the range of 0.0–6.0 McFarland units (0 – 180×107 cells/ml). Various calibration kits are available on request.
