Compact spectrofluorometer SP-F93

filter

Overview
The SP-F93 and SP-F93A are benchtop fluorescence spectrophotometers for quantitative and qualitative fluorescence measurements in laboratory environments. The models differ by available excitation filter sets and central wavelengths; both use LED excitation and a photomultiplier detector for sensitive emission measurement.

Features

• C-T manual grating monochromator with 1200 lines and non-spherical reflecting mirrors to improve sensitivity.
• High-intensity LED cold-light excitation with low fluorescence background; replaceable narrow-band excitation filters for selectable central wavelengths.
• Original Hamamatsu photomultiplier tube for sensitive emission detection and low noise.
• Automatic zero adjustment and automatic background subtraction; eight-stage sensitivity (gain) control and wide dynamic range for accurate measurement of small sample changes.
• Replaceable EX wavelength filter system (user-serviceable) for quick maintenance and configuration flexibility.
• RS-232C interface; optional data processing software for data storage, transmission and generation of standard calibration curves.
• Compact benchtop design and low power consumption suitable for laboratory and educational use.
