S 3255 UV/Vis Detector

The Sykam S 3255 UV/Vis Detector for high flow preparative chromatography configurable for routine use as well as research applications needing advanced optional functionalities

Sykam Logo


The Sykam S 3255 UV/Vis Detector is a single or optional dual channel variable wavelength detector with a wavelength range of 190 to 800 nm. Built around a high quality “moving monochromator” optics for minimal loss of light energy at any chosen wavelength, the result is a UV/Vis detector with high sensitivity and stability making the S 3255 suitable for routine as well as research applications.

An integrated wavelength program allows for free programming of different wavelengths within a run. A special feature of the S 3255 is the integrated peak detector with the possibility of direct control of external solenoid valves by means of an integrated 24 Volt output stage with a programmable delay function. Just adding a an automatic three-way valve from the Sykam S 6000 series allows for fraction collection or solvent recycling.

The preparative flowcell is available in stainless steel and in PEEK versions.
