Grant DEN-1/1B Densitometer, Cell Density Turbidity, For Tubes Outer 16/18mm
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.
---
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 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
