DW-F97 Series Fluorescence Spectrophotometer
DW-F97 fluorescent spectrophotometer is a new generation of high-performance molecular luminescence analysis instrument. The product structure is exquisite and has the characteristics of high detection sensitivity, fast scanning speed, wide spectrum measuring range, high dynamic range, fast 3D scanning, and so on. Easily meet the requirements in the field of material research, pharmaceutical analysis, biochemical and clinical testing, water quality analysis and control, food safety testing (dairy products, aquatic products, such as vitamin C, selenium, aflatoxin), and other areas.
Features of DW-F97 Fluorescent Spectrophotometer
- 1200 line diffraction grating emission monochromator. Its large aperture and non-spherical reflecting mirrors produce 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 sets of EX wavelength replacing the system. Carry on the maintenance expediently & can satisfy more choices and demands.
- 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 a glass filter.
- LED is a cold light source with longevity, lower background & reliability, and prevention thermo-pollution.
- Automatic zero adjustment and automatic background subtraction, Eight stage sensitivity adjustment, Real-time fluorescence reading display and concentration print out, the Extra wide dynamic range of fluorescence reading, and accurate measurement of minute changes in samples.
- Quality fine, less weight & measure, the test simply, particularly suitable for education& laboratory.
