Portable Densitometer, Cell density turbidity for 16 or 18mm tube

Additional information

DEN-1B Portable Densitometer (Cell density turbidity)
The Grant bio DEN-1 and DEN-1B are a compact benchtop densitometers (suspension turbidity meter) for measuring turbidity of cell suspensions in a variety of life science applications.

The densitometers are designed and factory calibrated to measure turbidity in the range of 0.5 to 4.0 McFarland units (DEN-1) 0.0 to >7.5 McFarland units (DEN-1B) with a small standard deviation. If required, it can deliver a wider measurement range (up to 15.00 McFarland units), but with a greater standard deviation.

• Measurement range: 0.5 to 4.0 McFarland units (DEN-1), 0.0 to >7.5 McFarland units (DEN-1B)
• Measurement time : 1 second
• Precision: ±3%
• Readings, conveniently shown in McFarland units, are clearly visible on the bright LED display
• Factory calibrated - retains calibration without power supply
• Can be user calibrated with commercial standards or cell suspensions prepared in the laboratory
• Designed for tubes with an outer diameter of 18mm. 16 mm tubes can also be accommodated by using the optional tube adaptor D-16
• Extremely compact design with small footprint and low profile - fits easily into the smallest workspace
• DEN-1b - either battery powered by 3 x AAA or via external power supply

Applications:

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.
