DEN-1 & DEN-1B Densitometer

Product catalog summary

Overview: The document provides detailed specifications and features of two densitometer models, DEN-1 and DEN-1B, designed for measuring the turbidity of cell suspensions in life-science applications.

Specifications:

Measurement Range: DEN-1 measures from 0.3 to 5.0 McFarland units, while DEN-1B measures from 0.00 to 6.00 McFarland units. Both can extend up to 15.00 McFarland units with increased standard deviation.
Precision: ±3% with a standard deviation of ±0.1 McFarland units at 3.00 McF.
Measurement Time: 1 second.
Light Source: LED with a wavelength of 565 ± 15 nm.
Tube Compatibility: Designed for 18 mm tubes, with an adaptor available for 16 mm tubes.
Power Supply: DEN-1B can be powered by 3 AA batteries or an external 12V power supply.
Display: DEN-1 uses an LED display with 0.1 McF resolution, while DEN-1B uses an LCD display with 0.01 McF resolution.
Dimensions and Weight: Both models have dimensions of 75 mm (h) x 115 mm (d) x 165 mm (w) and weigh 0.7 kg.

Features:

Factory calibrated with the option for user calibration using commercial standards or laboratory-prepared cell suspensions.
Compact design suitable for small workspaces.
Applications include determining cell concentration in fermentation, testing microorganism susceptibility to antibiotics, and measuring optical density.

Accessories:

DEN MCF STDS set of latex particle suspension McFarland standards (0.5/1.0/2.0/3.0/4.0) requiring D16 for use.
DEN MCF 18 STDS set of 5 McFarland reference standards for user calibration.
D16 spare tube adaptor for 16 mm tubes (included as standard).

Warranty: Both models come with a 2-year warranty.

Densitometers DEN-1 and DEN-1B Compact and efficient benchtop densitometers 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 0.3 to 5.0 McFarland units (DEN-1) 0.00 to 6.00 McFarland units (DEN-1B) with a small standard deviation. If required, they can deliver a wider measurement range (up to 15.00 McFarland units), but with a greater standard deviation. Ⅲ Measurement range: 0.3 to 5.0 McFarland units (DEN-1), 0.00 to 6.00 McFarland units (DEN-1B) Measurement time:...
