Compact and efficient benchtop densitometers for measuring turbidity of cell suspensions.
Measurement range: 0.3 to 5.0 McFarland units (DEN-1), 0.00 to 6.00 McFarland units (DEN-1B). If required, they can deliver a wider measurement range (up to 15.00 McFarland units), but with a greater standard deviation.
Standard deviation at 3.00 McFarland units: ±0.1 McF.
Wavelength: 565 ±15nm.
Precision: ±3%.
Measurement time: 1 second.
Sample volume: >2ml.
Light source: light diode.
Factory calibrated – retains calibration without power supply. Can be user calibrated with commercial standards or cell suspensions prepared in the lab.
Bright LED display.
Extremely compact design with small footprint and low profile.
Applications include 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.
Tube diameter: (external) 18mm dia.; (with D16 adapter) 16mm dia. D16 tube adapter for 16mm tubes is included.
Operating temperature range: 4 to 40ºC.
Dimensions (H x D x W, both models): 75 x 115 x 165mm. Weight: 0.9 kg.
