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.
