S23A Visible Spectrophotometer 340–950 nm

The S23A Visible Spectrophotometer is a compact benchtop analytical instrument designed for routine qualitative and quantitative analysis within the visible-light spectrum. It operates across a 340–950 nm wavelength range and supports measurement of transmittance, absorbance, concentration and concentration factor. The instrument can accommodate both rectangular cuvettes and suitable test tubes, making it practical for educational laboratories, environmental monitoring, clinical laboratories, research institutions and general chemical analysis.
