SP-F93 Fluorescence Spectrophotometer (Spectrofluorometer)
Features
- The emission monochromator adopts 1200 line diffraction grating. Its large aperture and non-spherical reflecting mirrors produces extra high sensitivity.
- High stable and long life xenon lamp and power source ensure high stable testing and wide range of spectrum.
- EX light use LED, match with the central wavelength of 365nm,420nm,475nm,525nm narrow banding-ultra low back grounding precision filters to consist 4 set of EX wavelength replacing system. The system can be replaced by customer, Carry on the maintenance expediently & can satisfy more choices and demand;
- The central wavelength of 365nm,420nm,465nm,515nm narrow banding-ultra low back grounding precision filters with low fluorescence background, it’s performance is better than glass filter;
- LED is a cold-light source with longevity, lower background & reliability, prevent from thermo-pollution;
- Automatic zero adjustment and automatic background subtraction; Eight stage sensitivity adjustment; Real time fluorescence reading display and concentration print out, Extra wide dynamic range of fluorescence reading, accurate measurement of minute changes in samples;
- RS-232C serial port interface attached, after option Data Processing Software Package it is convenient to store record & transmit data & draw up a standard operating curve;
- Quality fine, less weight & measure, test simply, particularly suitable for education & Lab.
