DENSITOMETER
- Compact benchtop densitometers for measuring cell suspension turbidity in life science applications.
- Measurement Range: 0.00 to >15.00 McFarland units with +3% precision.
- Fast Results: Measurement time of just 1 second.
- Bright LED Display: Clear McFarland unit readings.
- Factory Calibrated: Retains calibration even without power.
- User Calibration: Compatible with commercial standards or lab-prepared suspensions.
- Tube Compatibility: Designed for 18mm tubes, with optional adapters for 16mm
(D-16 included) & 12mm (A-12 sold separately). - Space-Saving Design: Small footprint, ideal for limited workspaces.
- Power Options (DEN-1B Only): Operates on 3 x AAA batteries or external power supply.
