Fluorescence Spectrophotometer

Fluorescence Spectrophotometer 1.LED cold light,long life and high reliability 2.Use high-performance signal receiving device

   Fluorescence Spectrophotometer

Introduction:

 

930N fluorescence spectrophotometer  The instrument is widely used in biochemistry, food, environmental protection, chemical industry and other departments for quantitative and qualitative analysis, is the ideal instrument selection for the school laboratory, factory inspection .

Main Features:

Emission monochromator grating with 1200 lines, large aperture aspherical mirror, covering 360-650nm wavelength range, continuous spectrum, the performance significantly better than the fluorescence spectrometer, can provide higher linearity of fluorescence, fluorescence sensitivity, the test more accurate data, in addition to quantitative tests can be achieved outside the sample can be qualitative; Use of high-performance signal receiving device, the high signal to noise ratio obtained;LED cold light source with excitation light source, with the center wavelength of 365nm, 420nm, 475nm, 525nm 4 precision narrow-band filter composed of 4 ultra-low background excitation wavelength can replace the system for the user replaceable, easy maintenance, to meet more choice and need;Configuration of four narrow-band filter used in all precision ultra-low background interference filter, low background fluorescence, the performance greatly superior to the commonly used glass filters;LED cold light long life and high reliability, relative to the usually low background heat source to prevent thermal pollution, and expand the dynamic range of fluorescence;Auto-zero, automatic deduction of the background; eight out sensitivity adjustment; real-time fluorescence value, fluorescence value of the wide dynamic range, determination of changes in the sample;RS232 communication port to carry the host, optional dedicated data processing software package to perform data storage, recording, transmission and standard curve, quantitative analysis and other functions;Stable and reliable quality, small size, light weight, easy to operate and the test is very suitable for teaching and student experiments.
