Fluorescence Spectrophotometer LFS-A11 Catalog

Overview

Fluorescence Spectrophotometer LFS-A11 is a high performance equipment with a 150 W Xenon Lamp for providing sufficient light intensity signal to detect sensitivity. It is built for maintaining best possible accuracy. It contains characteristics like Ultra scanning speed, ultra high resolution, and ultra-high wavelength accuracy to meet most of the measurements. Quantum yield is also available for this fluorescence spectrophotometer.

Features :

Horizontal slit optical design with finite luminous detection efficiency and high SNR
Water Raman peak SNR better than 350: 1 (P-P) or 1000: 1 (RMS)
Standard 10 mm square sample cell utilizes minimum sample volume of 0.5 mL
Wavelength scanning speed is flexible and can reach up till 60000 nm / min
Adjustable bandwidth feature
Accessories are available for Fluorescence Quantum Yield
Software is versatile enough to offer functions like fluorescence 3D scanning, equal wavelength difference synchronous scanning, and equal wave number difference (constant energy difference) synchronous scanning
Synchronous scanning function require pro version software
Multiple accessories provided
Best quality assurance given by using 150 W Xenon Lamp, to provide sufficient light intensity signal to detect sensitivity
Unstable samples is analysed via built-in optical gate and built-in frequency filter
