Product Description
The tM550 is an optical density measuring instrument that presents results in McFarland units, also known as a McFarland nephelometer or densitometer. The nephelometer uses a light source to illuminate the sample and detects the intensity of light passing through the sample via a photoelectric sensor. This intensity is directly proportional to the turbidity or density of the sample, and the optical density of the sample is calculated based on the detected intensity of light. The nephelometer can be used to measure the turbidity of cell suspensions within the range of 0.0–5.0 McFarland units (0-150 ×10^7 cells/ml). It enables rapid and reliable preliminary detection in fields such as microbial identification and cell concentration measurement.
