Product Overview

The 930F model is a variable-wavelength-adjustable fluorescence spectrophotometer, with a standard excitation (EX) wavelength of 365 nm, an emission (EM) wavelength range of 300-700 nm and a spectral bandwidth of 12 nm.The 7-inch color touch screen applies professional technology to empower effective human-computer interaction. The USB communication port is used for online operation to facilitate the further calculation and processing of data and time saving,with the universaldata processing software package, which is optional.
The instrument is widely used in biochemical, medical, food, environmental protection, chemical and other departments for quantitative and qualitative analysis. It is an ideal instrument for laboratory and factory inspection.


Main Features

● The emission monochromatoradopts a 1200 g/mmgrating and a large-aperture aspherical reflector with a particularly high sensitivity.

● The high-brightness and long-lasting LED light source ensures the high stability of the test.

● A newly designed sample cell holder ensures a wide variety of test methods.

● The high-performance photomultiplier tube is used for the optimal signal-to-noise ratio.

● Automatic zeroing and background deduction.

● Real-time display of fluorescence and concentration values.

● Direct reading ofsingle point standard concentration.

● Multi-point linear regression can be performed at any time with the universal data processing software package.

● The extremely wide dynamic range of fluorescence can accurately determine small changes in the sample.
