Compact Fluorescence Spectrophotometer - Dual Monochromator Fluorometer - 200-900 nm - 48000 nm/min

The Master Science Compact Fluorescence Spectrophotometer is a small-footprint molecular luminescence instrument with a double-monochromator layout. Excitation and emission both cover 200 to 900 nm, driven by a 150 W xenon lamp and a photomultiplier tube detector.

Scanning runs at up to 48000 nm/min, so a classic fluorescence spectrum takes about a second and a three-dimensional spectrum about a minute. Three versions differ in slit options, wavelength accuracy and sensitivity.
