Beckman Coulter DU 520

This Beckman Coulter DU 520 is a used UV-Visible spectrophotometer from the well-regarded DU series, a line of instruments that earned a strong reputation in clinical and research laboratories for their accuracy and durability. The unit has been previously used in a working lab and is offered here in functional condition for buyers who want proven Beckman Coulter optical performance at a fraction of the cost of new equipment. It is built around a stable optical bench designed to deliver consistent wavelength accuracy across repeated measurements. The DU 520 supports a broad set of laboratory workflows including quantitative absorbance analysis, enzyme kinetics, DNA and protein quantification, and general photometric testing. Its onboard software and menu-driven interface allow technicians to set up methods and run samples efficiently, while the instrument's build quality reflects Beckman Coulter's long history of precision engineering in analytical chemistry equipment. Labs that have relied on this platform value its consistency across long production runs and multi-shift operation. This pre-owned DU 520 is a good fit for clinical laboratories, university research groups, and quality control departments that need a trustworthy spectrophotometer without the price tag of a brand-new system. It represents a practical way to bring proven analytical capability into a lab that is expanding its testing capacity or replacing an aging instrument.
