UV-Visible Spectrophotometer 756S, ±0.5 nm Wavelength Accuracy (CAT#: STEM-AL-8838-ZJF)

The 756S is a spectrophotometer intended for automatic scanning ultraviolet-visible spectroscopy. It measures sample absorbance and transmittance by selecting wavelength-resolved ultraviolet or visible light. The optical system uses a diffraction-grating C-T monochromator. The stated wavelength coverage is 190-1100 nm. The source specifies automatic wavelength scanning together with absorbance and transmittance measurement performance. USB and serial interfaces support data storage, computer connection, and printer communication. The normalized record retains only technical information supported by the source. Overall, the instrument provides a scanning UV-visible platform for general laboratory analysis.
