Rugged, economical, fixed-wavelength detector for analytical or preparative HPLC. A front panel knob allows selection of the wavelength to monitor the absorbency of almost any sample.

Provides detection at 254 and 280 wavelengths.
Fixed-wavelength design provides increased sensitivity and durability.
Event-marking function allows convenient marking of the point of injection or advance of a fraction collector on the recorder or data system.
10-mm pathlength analytical flow cell offers excellent sensitivity ranging from 0.001–1 AUFS (Absorbance Units, Full Scale).
Dual-beam optics ensure equal illumination of both the sample cell and the reference aperture to maintain baseline stability at high sensitivity.
Easy-to-change lamp and filter assemblies for selecting wavelengths.
Easy, one-step baseline function helps reduce operating and setup time.

Applications
Biological samples, industrial chemicals and small-molecule analysis via HPLC.
