Biosan DEN-1 densitometer (suspension turbidity detector) includes A-16 adapter for 16 mm tubes, external power supply unit 230VAC 50/60Hz Euro plug
- Densitometer is designed for measurement of cell suspension's turbidity in the range of 0.3–5.0 McFarland units (100×106 – 150×107 cells/ml).
- Densitometer provides the opportunity to measure solution turbidity in a wider range (up to 15.0 McFarland units) however, it is necessary to remember that in this case the standard deviation values increase.
- The operation principle is based on measurement of optical density with digital presentation of results in McFarland units. The unit is calibrated at the factory (for operation with 16 mm diameter glass tubes) and keeps calibration without power supply. However, if necessary it is possible to calibrate the unit by 2–6 points in 0.5–5.0 McFarland unit range. Both commercial standards (e.g. produced by BioMerieux, Lachema, etc.) and the cell suspensions prepared in a laboratory can be used for calibration.
