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 of 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 printout, 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.
