Product Introduction
The YP-MNTU is an optical density measuring instrument that displays results in McFarland units, also known as a McFarland turbidimeter. The densitometer uses a light source to illuminate the sample and a photoelectric sensor to detect the intensity of light transmitted through the sample. This intensity is proportional to the turbidity or density of the sample, and the optical density is calculated based on the detected light intensity.
The densitometer can measure the turbidity of cell suspensions in the range of 0.0–5.0 McFarland units (0–150 ×10⁷ cells/mL). It enables fast and reliable preliminary testing in applications including microbial identification and cell concentration measurement.
Product Applications
- Cell Concentration MeasurementThe densitometer can measure the concentration of microorganisms such as bacteria or yeast in microbial cultures, which is critical for monitoring microbial growth during fermentation.
- Antibiotic Susceptibility TestingIt helps evaluate the susceptibility of microorganisms to antibiotics. By measuring the turbidity of microbial cultures, the response of microorganisms to antibiotics can be determined.
- Microbial IdentificationIt provides a rapid and reliable method for preliminary microbial identification. Different microbial species may produce different turbidity values, allowing differentiation by measurement.
- Absorbance MeasurementIt can measure the absorbance of microbial cultures at specific wavelengths, which is useful for studying the content or changes of specific components in cultures.
- Color Solution Concentration EstimationIt can quantitatively estimate the concentration of colored solutions that absorb green light, which is helpful when using dyes or indicators in microbiological experiments.
