ELICO's SL-174 spectrofluorometer is an instrument which takes advantage of fluorescent properties of some compounds in order to provide information regarding their concentration and chemical environment in a sample. A certain excitation wavelength is selected, and the emission is observed either at a single wavelength, or a scan is performed to record the intensity versus wavelength, also called an emission spectra
- Microprocessor based, User friendly, Menu Driven with Printer Interface
- Dual Monochromator Design.
- Four cell turret sample holder for Fluoroscence measurement.
- Precise settings of Wavelengths and Slit widths in both Excitation and Emission Monochromators.
- Compliance with IP/BP/USP standards.
- Supports Fluroscence Polarization modules (Single Cuvette sample holder)
- Absorbance, Fluorescence and Polarization.These three varieties of accessories are application oriented and are interchangeable.
- Optional PC compatibility with RS232C Interface and MS Windows® based Software for Data Acquisition, Processing, Storage, Retrieval & Interpretation of Data.
