EziLab offers the UV-Visible Spectrophotometer EZL-US132, a double beam pharma UV Vis reader scanning 190 to 1100 nm at a fixed 2 nm bandwidth while a reference path cancels lamp drift. Wavelength accuracy holds ±0.5 nm with repeatability within 0.2 nm, photometric accuracy reaches ±0.002 Abs below 0.5 A, stability sits at ±0.001 A per hour, noise at 0.0005 A, and stray light under 0.05 % T. Absorbance reads -0.4 to 4 A on an 800 by 840 color touch screen, the optics sit on a rigid 8 mm aluminum base, calibration runs automatically, encryption guards methods, a four-position holder takes cuvettes, and results print or export over USB. It packs at 860 by 660 by 465 mm and 35 kg. Choose it over the selectable-bandwidth sibling when one 2 nm setting covers the pharmacopoeia methods. Pharmaceutical QC labs run content assays on it, stability groups track degradation over months, biochemistry labs quantify proteins, and clinical labs read colorimetric kits. Routine methods include assay by absorbance, release profiles, kinetics, and spectral scans. Spectrophotometer leads to Double Beam UV-Visible Spectrophotometer for sibling readers; ask how long the lamps need before a method run begins.
