Double-Beam UV-Visible Spectrophotometer UV1920, 2 nm Bandwidth (CAT#: STEM-AL-8837-ZJF)

The UV1920 is a spectrophotometer intended for ultraviolet-visible absorbance and transmittance analysis. It measures sample absorbance and transmittance by selecting wavelength-resolved ultraviolet or visible light. The optical system uses a dual-path optical design comparing sample and reference signals. The stated wavelength coverage is 190-1100 nm. The 2 nm bandwidth provides a fixed spectral-resolution configuration for routine analysis. A color touchscreen is used for instrument control and data viewing. The normalized record retains only technical information supported by the source. Overall, the instrument provides a double-beam UV-visible platform for stable routine measurement.
