Grant Bio McFarland DEN-1 Densitometer

• Determining cell concentration in fermentation or culture processes.
• Assessing microbial susceptibility via turbidity changes.
• Identifying microorganisms in test systems.
• Measuring optical density/turbidity at a fixed wavelength for dyes or suspensions.

Typical measurement range

Units of this type commonly measure in McFarland units (e.g., 0.0 to 15.0 McFarland) or absorbance.

Power supply

Densitometers for laboratory use typically operate on standard mains power, commonly 230V AC for the UK market.

Footprint

For this class of benchtop instrument, a compact footprint is typical, designed for laboratory benches.

Sample volume

Commonly designed for small sample volumes, often utilising standard test tubes or cuvettes.

Calibration

Units typically feature user calibration capabilities, often with pre-calibrated standards.

Interface

A digital display and simple button interface are commonly found on units of this type for ease of use.

• What is a McFarland Densitometer used for?

  A McFarland Densitometer is primarily used in microbiology and life sciences to measure the turbidity or optical density of cell suspensions, such as bacterial or yeast cultures.

• How does a densitometer measure turbidity?

• Is this unit suitable for industrial food processing applications?

• What kind of maintenance does a densitometer require?

• Can this densitometer be connected to a computer for data logging?

Densitometers are regarded as dependable instruments for measuring optical density in analytical work. Buyers typically value their precision and reliability across laboratory settings. When purchasing used models, condition of the light source and detector alignment merit close inspection, as recalibration may be necessary. Industry sentiment recognises these instruments for consistent performance and straightforward operation. Build quality generally remains sound through extended use, making them sensible acquisitions for facilities requiring accurate density measurements without significant capital expenditure.
