Shimadzu RF-535

This used Shimadzu RF-535 is a fluorescence detector from Shimadzu's earlier generation of HPLC instrumentation, designed to provide sensitive detection of fluorescent compounds within classic Shimadzu LC system configurations. It uses a xenon lamp source and adjustable wavelength optics to isolate excitation and emission signals from column effluent, and it has a long track record of dependable operation in laboratories that have kept legacy chromatography systems running for specialized or long validated methods. In practice, the RF-535 sits in line after the analytical column and translates fluorescence emission from target compounds into a signal that feeds the system's chart recorder or data station, supporting both qualitative screening and quantitative analysis. It has traditionally supported work in pharmaceutical analysis, natural product research, and academic laboratory settings where fluorescence detection offers better selectivity and sensitivity than UV absorbance alone. Because it was designed for earlier Shimadzu hardware, it is most often found paired with corresponding vintage pumps and injectors. Offered here in used condition, this RF-535 comes from a laboratory that has since upgraded its chromatography fleet. It is a good fit for labs still running legacy Shimadzu systems, educational laboratories maintaining older instrumentation for teaching purposes, or technicians seeking an affordable replacement unit to keep an established method operating.
