Used BECKMAN COULTER DU-640 #293625594 for sale

BECKMAN COULTER DU-640 spectrophotometer is an ultraviolet (UV) and visible (VIS) light spectrophotometer capable of measuring low concentrations of analytes in samples. DU-640 contains two xenon flash lamps, each of which is powered by up to 6 kilovolts of potential. The device is used for the measurement of concentrations of compounds in the spectral range from 190 to 1100 nanometers (nm). BECKMAN COULTER DU-640 can be used with a variety of sample holders, including standard disposable cuvettes, microplates, and slotted lids. The microplates allow for the use of larger volumes of sample, as well as faster readings. The device's dual-beam operation is able to provide measurements in both the UV and VIS spectrum simultaneously and in a variety of sample formats. The readings are directed to an internal computer which uses advanced proprietary software to process them. The spectrophotometer is also equipped with a laboratory-grade, fan-cooled, curved-aperture design, allowing it to obtain readings with higher precision and accuracy than other similar models. Its optics are completely automated, meaning the user can select the optimal and most precise angle of incidence and angle of measurement for their sample. The data output can be configured for direct measurements and for multistep protocols. The spectrophotometer can assess concentration of particles and molecules from a variety of sources, from purified laboratory substances to complex mixtures of components. When used in combination with software programs and chemometric analysis, it can be used to evaluate color and spectral data from a variety of sources with utmost precision. In summary, DU-640 spectrophotometer is an invaluable tool for measuring concentrations of substances with the utmost precision. With its dual-beam, fan-cooled design, automated optics and multistep protocols, this device can quickly and accurately evaluate, measure, and analyze any sample.
