Time-integration spectrofluorometer SP-F98

fluorescence lifetime measurement

Short description
SP-F98 fluorescence spectrophotometer (spectrofluorometer) providing rapid wavelength scanning and high sensitivity for laboratory and industrial fluorescence analysis.

Key features

• High signal-to-noise ratio: horizontal-beam design with large-diameter concave-grating monochromator for improved luminous efficiency; water Raman peak S/N ≥250 (P-P) or 800 (RMS).
• Ultra-fast scanning: wavelength scanning up to 60000 nm/min enables 3D fluorescence spectra acquisition within 1 minute.
• Adjustable spectral bandwidths: excitation and emission bandwidths selectable at 1, 2, 5, 10 or 20 nm for high-resolution measurements.
• Accurate wavelength control: precision drive and automatic calibration with wavelength accuracy ±0.4 nm and repeatability ≤0.2 nm.
• Advanced scanning modes: 3D fluorescence scanning, time-resolved 3D scanning, synchronous wavelength-difference scanning and constant-energy differential synchronous scanning.
• Low sample volume: minimum 0.5 mL using a 10 mm cuvette.
• Quality components: 150 W xenon lamp and Hamamatsu photomultiplier detector.
• Large sample chamber and programmable optical gate to stabilize photo-reactive signals and ease accessory handling.
• Comprehensive measurement accessories included (cuvette holders, multi-fluorescent sample holder, 200 µL microcentrifuge tube adapter, capillary adapters, semi-automatic injection fluorescence attachment, film and powder holders, sheathed cell holder, etc.).
