Beckman DU 800 Spectrophotometer, 190 to 1100 nm, Beckman Coulter (CAT#: STEM-SPO-0039-LGZ)

The Beckman DU800 Spectrophotometer is a high-performance system capable of handling complex analysis and basic functions. This model has a variety of applications in the life sciences, academia, biotechnology, and pharmaceutical industries. The instrument control, data processing and restoration of Beckman DU 800 are all managed by computer. This type of data management is suitable for both quantitative and qualitative analysis.

The integrated interfaces used by the DU800 allow for ease of use and enhanced user experience. The model is also equipped with performance-enhancing features, including immediate access to system functions and continuous display of status and method parameters.

The system is equipped with a scheduler for efficiency. The DU 800 light source scheduler is responsible for automatically switching between UV lamps and visible light lamps at a specified time. The built-in performance verification scheduler enables programmed system warm-up and specified test procedures at any given time. The cell-matching feature of the spectrophotometer enables minor variance adjustments when working with multiple cells. The DU 800 performs quick reading and scanning procedures without having to open other applications.
