U.V.S Spectrophotometer with Standard Specification G-UVS470
Brand:QINSUN
Model:G-UVS470
Introduction
A UV-Visible Spectrophotometer is an analytical instrument used to measure the light absorption characteristics of substances in the ultraviolet and visible wavelength regions. By detecting the degree of light absorption at different wavelengths, it enables both qualitative and quantitative analysis of substance concentration and composition. The instrument features high sensitivity, fast analysis speed, and easy operation.
Application
(1) For formaldehyde test of different type of fabrics
With shaking bath/ device, reagents, accessories and desktop /laptop computer.
(2) Software to create standard curves and absorbance vs. time graphs and must include wavelength scanning feature.
Must Include:
a 2.1-m (7-ft) detachable cord, dust cover, four-position 10-mm cuvette holder, four glass cuvettes, and two quartz cuvettes
