Used BECKMAN COULTER DU-640 #9029946 for sale

BECKMAN COULTER DU-640 spectrophotometer is a powerful, versatile and cost-effective instrument designed to perform a wide range of biochemical and biological measurements. It utilizes a precision Xenon flash lamp to provide an ideal source of intense and uniform light over a wide range of wavelengths (UV to VIS). The spectrophotometer measures the intensity of light transmitted or reflected from a sample over a range of wavelengths and displays the results on a graph. From this, a range of information can be gained, such as the amount of a chemical in a sample, the concentration of a colorant in a pigment, and the composition of a mixture. DU-640 offers an intuitive user interface with easy-to-use software for measuring absorbance and concentration ranges from 0.0000 to 999.999 AU (absorbance units). The high-precision optics ensure superior signal-to-noise ratios while the low stray light levels increase the accuracy of the measurements. The instrument features both visible and UV scanning modes allowing for multiple measurements in different wave ranges. The spectral range is adjustable from 250 to 900nm and the optical frontend offers an adjustable slit width of 0-4nm allowing for more precise bandwidth control. It also features a built-in printer that can generate comprehensive reports on demand as well as a specialized 8-position cell changer that offers automatic sample testing capabilities. BECKMAN COULTER DU-640 spectrophotometer is a powerful and easy-to-use instrument making it an ideal choice for both routine biochemical measurements and more precise nanoscale studies. Its combination of features makes it a versatile choice that can be used to measure a wide range of parameters and concentrations for even the most exacting applications. Coupled with its ease of use, cost-effectiveness and advanced optics, DU-640 is the ideal choice for users in a wide range of industries.
