Bio-Rad BioLogic QuadTec UV-Vis Detector

This used Bio-Rad BioLogic QuadTec UV-Vis Detector is a multi wavelength detection module designed to complement BioLogic chromatography systems during protein and biomolecule purification. It monitors column eluate at up to four wavelengths simultaneously, which allows researchers to track multiple chromophores or protein features in a single chromatography run rather than relying on repeated single wavelength scans. This capability makes it especially useful for complex purification schemes where more than one analyte needs to be tracked in real time. The QuadTec detector integrates directly into existing BioLogic pump and fraction collector setups, giving labs a straightforward way to expand detection capability on an established chromatography line. Its flow cell design is built to handle the buffers and solvents typical of biologics purification without introducing excessive dead volume, helping preserve peak resolution during separations. Because wavelength selection is user configurable, the detector adapts to a wide range of protein purification and analytical development protocols. Offered here as a used unit from an active laboratory, this detector is well suited to labs already running BioLogic platforms who want to add or replace multi wavelength detection capability. It provides a cost effective way to extend the analytical reach of an existing chromatography workflow without purchasing an entirely new system. The unit is sold in working condition and ready to integrate into a compatible purification line.
