Used BECKMAN COULTER DU-640 #293606968 for sale

A BECKMAN COULTER DU-640 spectrophotometer is an analytical device used to measure the intensity of a light beam across a range of wavelengths. This advanced equipment is employed to quantify the concentration of components in a sample solution by measuring its absorbance of light at different wavelengths. The main components of a spectrophotometer consist of a light source, monochromator, detector, and software for data processing. DU-640 is typically configured with a Deuterium UV-Vis Lamp as the light source which provides light of similar wavelengths to sunlight, but with a far longer lifetime than regular lamps. A proprietary variable slit monochromator is used to accurately select and pass desired wavelengths of light onto the sample. This monochromator utilizes a double-precision servo-controlled optical system to ensure optimal selectivity and spectral accuracy. Once the sample has passed through the monochromator, it is received by a dual-beam photodiode array detector which measures energy passing through the sample. This detector allows for simultaneous measurements of lower concentrations and is capable of operating at a wide range of sensitivities. To assist the user, BECKMAN COULTER DU-640 also comes loaded with EasyMax software, allowing for a wide range of operations such as the measurement of concentration and the determination of concentration ranges. For additional control, the user is able to adjust the function of the spectrophotometer's outputs through external sources such as an analog input, an RS-232 data port, and a network-ready connection. The device also allows for manual control over all settings through an easy-to-use, touch-screen terminal. In short, DU-640 spectrophotometer is a powerful device that allows for highly accurate measurements of the concentration of components in any solution. Its state-of-the-art components, along with its robust software and user friendly controls, sets BECKMAN COULTER DU-640 up to be a reliable and capable piece of equipment for any lab.
