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

Beckman DU 800 Spectrophotometer, 190 - 1100 nm, model DU 800, is manufactured by Beckman Coulter. The Beckman DU800 Spectrophotometer is a top performing system capable of handling both complex analyses and basic functions. This model has various applications in life sciences, the academe, biotechnology and the pharmaceutical industry. Instrument control, data handling and reduction for the Beckman DU 800 are managed through a computer. This type of data management is suitable for quantitative and qualitative analyses.
The integrated interface utilized by the DU800 allows for ease of use and the enhancement of user experience. This model is also equipped with features that increase performance including immediate access to system functions and the continuous display of both status and method parameters.
This system is fitted with schedulers to heighten efficiency. The DU 800 source scheduler is responsible for automatically switching the UV and visible lamps at specified times. The built-in Performance Validation Scheduler is capable of programmed system warm-ups and specified testing procedures at any given time. The cell matching feature of this spectrophotometer enables minor difference adjustments when dealing with multiple cells. The DU 800 carries out quick reading and scanning procedures without having to open other applications.
