St. John Associates' Fluoro-Tec fluorometer provides a cost-effective and versatile means of implementing fluorescence-based techniques in discrete sample analysis, liquid chromatography detection (HPLC) and flow injection analysis (FIA) -- both continuous-flow and bubble-segmented. It also performs well as a nephelometer.
St. John Associates offers two Fluoro-Tec models: the original bench Fluoro-Tec and the Field Fluoro-Tec. Both models share the same feature set and accessories, but the field unit offers portability, weather-resistance and battery power capability.
The FLUORO-TEC was designed for use in the analysis of discrete samples (cuvettes) and for use as the detector in flow systems (flow cells) with no compromise to either application. Convert from one application to another in seconds, with no awkward sheetmetal covers, no cabinets to open, and no add-on external power supplies. Cuvette adapters are available for capillary tubes, 6 x 50mm round tubes, 10 x 75mm round tubes, and 1 x 1cm rectangular spectrofluorometer cells. A front-surface adapter for solid samples is also available. Flow cells for HPLC are available with 18 and 70 microliter volumes and several large-volume cell configurations are available for flow injection analysis and for continuous-flow and water analysis applications. A wide range of excitation wavelengths is provided by your choice of a mercury or a tungsten/halogen lamp. Lamp changes require only the switching of the lamp itself; no power supply changes are required. Dozens of excitation and emission filter combinations are available. Photodetection is via the industry standard 9-stage side-window photomultiplier tube. Models available span the wavelength range from deep UV to near IR.
