Overview
Product Overview
The AELAB F93 is a Fluorescence Spectrophotometer designed for sensitive and selective fluorescence analysis, including trace-analysis applications in medical science, pharmaceuticals, biochemistry, food analysis, pollution analysis, and organic and inorganic chemistry.
The F93 uses an LED excitation source with a standard central wavelength of 365nm. Its emission monochromator adopts a 1200-line diffraction grating together with a large optical aperture and non-spherical reflecting mirrors to provide high sensitivity.
The instrument provides an emission wavelength range of 360~650nm, 12nm bandwidth, wavelength accuracy of ±2nm and wavelength repeatability of ≤1nm. Automatic zero adjustment, automatic background subtraction and eight-stage sensitivity adjustment support routine fluorescence measurement.
