Description
It’s Purpose:
The Beckman DU-520 UV/VIS spectrophotometer is a laboratory instrument used to measure the absorbance or transmittance of light through a sample. It operates in both the ultraviolet (UV) and visible (VIS) ranges, typically from 190 to 1100 nanometers (nm).
The DU-520 features a double-beam design, which allows for accurate measurements by comparing the light intensity of a reference beam to that of a sample beam. It has a photomultiplier detector that detects the amount of light that passes through the sample, and a monochromator that selects a specific wavelength of light for measurement.
Acme’s Summary:
The DU-520 also includes a range of features designed to optimize performance and ease of use, such as a digital display, automatic zeroing, and the ability to store and recall multiple methods and data sets.
