EziLab offers the UV-Visible Spectrophotometer EZL-US118, a single beam routine UV Vis meter that scans 200 to 1000 nm at a fixed 4 nm bandwidth through a 1200 line grating onto a silicon photodiode. Wavelength accuracy and repeatability both sit at ±0.5 nm, photometric accuracy at ±0.5 % T, stability at ±0.002 A per hour, baseline flatness at ±0.0015 A, and stray light under 0.05 % T. Absorbance reads -0.3 to 3 A with transmittance and concentration modes, a five-position cell holder takes standard cuvettes, a pre-aligned deuterium lamp swaps without realignment, a solvent-resistant keypad and LCD run the unit, and USB and a parallel printer port carry results. It packs at 57 by 45 by 31 cm and just 14 kg. Choose it over the 2 nm sibling when throughput of simple absorbance checks matters more than peak separation. Pharmaceutical QC labs run content uniformity on it, biochemistry groups quantify proteins, clinical labs read colorimetric kits, and university teaching labs train students on Beer-Lambert work. Routine methods include single wavelength absorbance, standard curve quantitation, kinetics, and spectral scans. Quartz cuvettes are needed below about 340 nm; price them with the unit from Spectrophotometer or Single Beam UV-Visible Spectrophotometer listings.
