Fluorescence Spectrophotometer - Xenon Lamp Spectrofluorometer - 200-900 nm - 60000 nm/min Scan

The Master Science Fluorescence Spectrophotometer is a high-performance molecular luminescence instrument with excitation and emission monochromators that both cover 200 to 900 nm. A 150 W xenon lamp and a photomultiplier tube detector supply the intensity and sensitivity.

Its horizontal-slit optics give a water Raman signal-to-noise ratio of at least 350:1 peak-to-peak. Slits are selectable from 1 to 20 nm, scanning reaches 60000 nm/min, and a standard 10 mm cell needs only 0.5 mL of sample.
