Description
EziLab supplies the UV-Visible Spectrophotometer EZL-US131 for pharmaceutical laboratories that need standard single beam absorbance measurement across the full 190-1100nm range at 2nm bandwidth. This UV vis spectrometer covers routine absorbance and concentration work at a lower cost per unit than the double beam models in this catalog, without the drift-correction hardware those units carry for extended scan sessions. Pharmaceutical QC labs favor this configuration since it's simpler to operate and maintain while still covering the same UV and visible-light span as pricier double beam instruments. It suits single-sample, single-method workflows where lamp drift over a shorter scan session isn't a practical concern, distinct from the double beam models built specifically to correct for that drift during longer kinetics studies or multi-point calibration runs. That standard 190-1100nm/2nm single beam configuration matches other listings in this catalog sharing this exact specification, positioned as the foundational single beam entry point across several product URLs. Pharmaceutical QC labs running quick single-point absorbance checks get full functional coverage from this configuration without paying for double beam correction they don't need at that testing scope. See the UV Vis Spectrometer and UV-Visible Spectrophotometer ranges for routine single-beam absorbance testing needs across USA pharmaceutical laboratory settings.
