Description
EziLab supplies the UV-Visible Spectrophotometer EZL-US122 for pharmaceutical QC laboratories and research facilities that need lamp-drift correction during extended scan sessions. This UV spectrophotometer corrects for lamp drift in real time across the full 190-1100nm range at a selectable 1-2nm bandwidth, letting operators trade resolution for light throughput depending on the sample — narrow bandwidth for closely spaced spectral peaks, wider for faster scans on more forgiving samples. This flexibility makes it the better fit for method-development work and multi-application labs running different assay types on the same instrument, distinct from the single beam models in this catalog built for routine single-sample work without needing drift correction. Pharmaceutical QC labs running extended kinetics studies or multi-point calibration curves, where lamp stability over time genuinely matters, get the standard double beam correction here, positioned as the original wide-bandwidth double beam configuration in this catalog below the finer 1nm and 1.8nm bandwidth variants and the extended 0.1-5nm PMT-detector model covered elsewhere. See the UV Spectrophotometer and UV-Visible Spectrophotometer ranges for research-grade absorbance testing needs across USA pharmaceutical and academic laboratory settings.
