BS-050102-AAK | Densitometer for suspension turbidity quantification (DEN-1)








Key Features

  • Ideal for the measurement of turbidity of solutions containing cells or microorganisms
  • Measures turbidity over a wide range of McFarland units at 565 nm
  • LED light source
  • Suitable for glass and transparent plastic 12 mm tubes (with included adapter), 16 mm tubes (with included adapter) or 18 mm tubes without an adapter
  • LCD display
  • Instrument is factory calibrated using 16 mm glass tubes.
  • External power supply

Description

The DEN-1 densitometer has been developed to measure the turbidity of a solution containing cells or microorganisms. Turbidity is measured over a range of 0 - 15.0 McFarland units which equates to 0 - 150 x 107 cells/mL).

Key applications for the DEN-1 include:

  • Measurement of cell concentration (e.g. bacteria and yeast cells) during fermentation
  • Determination of microorganism sensitivity to antibiotics
  • Microorganism identification using various test systems
  • Measurement of absorption at fixed wavelength
  • Quantitative estimation of concentration using solutions that absorb green light

The DEN-1 is compatible with glass and transparent plastic 12 mm tubes (with included adapter), 16 mm tubes (with included adapter) or 18 mm tubes without an adapter. The instrument is factory-calibrated for use with 16 mm diameter glass tubes with calibration parameters being stored in the DEN-1 in case the unit needs to be reset to factory calibration settings.
