Description
The Beckman Coulter DU 600 Series Spectrophotometers are a microprocessor controlled spectrophotometer intended for use in quantitative and qualitative biological research and industrial procedures that required spectrophotometric measurements in the UV-visible region of the electromagnetic spectrum.

The DU 600 Series operates in the wavelength range of 190 to 1100 nm. Models of the instruments are available with either a monochrome or a color video display. Data storage on a 3.5 diskette is optional. Accessories to configure the instrument for specific application needs are available in the marketplace.

The instrument features a graphic video display, which provides operational information using windowing techniques, and a mouse for operator control.

The instrument has two rapid reading modes: RediRead for taking readings at a fixed wavelength and RediScan for making a wavelength scan.

The instrument has three standard Routine Measurement modes, which are: Fixed Wavelength, Wavelength Scan, and Kinetics/Time. Other various Application modes are available, such as Protein Analysis, Nucleic Acid, Single Component Quantitative Analysis, and Performance Validation.
