Fluorescence Spectrophotometer
Model:DW-F93/F93A
DW-F93/ F93A fluorescence spectrophotometer adopts a cold light source and a replaceable interference filter system, and the receiver adopts a high-performance photomultiplier tube. It has high detection sensitivity, high selectivity, and a user-friendly functional operation interface. Fast and high-precision fluorescence intensity measurement, a variety of excitation light source components can meet the testing needs of most users, cost-effective, especially suitable for university laboratory teaching demonstrations and student experiments, it is the first choice for upgrading of the majority of user units in higher education systems.
Features
- 1200 line diffraction grating emission monochromator . Its large aperture and non-spherical reflecting mirrors produces extra high sensitivity.
- 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. Carry on the maintenance expediently & can satisfy more choices and demand.
- The central wavelength of 365nm,420nm,475nm,525nm narrow banding-ultra low back grounding precision filters with low fluorescence background. Its 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.
- Quality fine, less weight & measure, test simply, particularly suitable for education & laboratory.
