G GRANT DEN-1 and DEN-1B densitometers
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.
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.
About
The densitometers are designed, and factory calibrated to measure turbidity in the range of McFarland units. For DEN-1 and DEN-1B it is 0.00 to >15.00 McFarland units with a small standard deviation.
- Measurement range: McFarland units 0.00 to >15.00
- 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 and 12mm tubes can also be accommodated by using the optional tube adaptor D-16 (included) or A-12 (sold separately)
- Extremely compact design with small footprint and low profile - fits easily into the smallest workspace
- DEN-1B - either battery powered by 3 x AA or via external power supply
