Fluorescence Spectrophotometer LX11FS
Description
Fluorescence Spectrophotometer LX11FS is a new generation of high-performance molecular luminescence analytical instrument with a 150 W xenon lamp and photoelectric multiplier tube detectors that provide sufficient light intensity signal and sensitivity. Equipped with Horizontal slit optical design with finite luminous detection efficiency and high SNR and adjustable bandwidth (1/2/5/10/20 nm) feature. It has characteristics like Ultra-high scanning speed, resolution, and wavelength accuracy to perform most of the precision measurements. Wavelength scanning speed is flexible and can reach up to 60000 nm/min.
