Description
EziLab offers the Visible Spectrophotometer EZL-VS100, a single beam lab spectrophotometer reading 325 to 1000 nm at a 4 nm spectral bandwidth through a 1200 line/mm grating. Wavelength holds within 2 nm with repeatability of 0.5 nm or better, photometric readings stay within 0.5% T, and stray light is 0.2% T or less at 360 nm. A tungsten lamp, silicon photodiode, 128 by 64 dot LCD, and USB plus parallel ports run under microprocessor control on 85 to 250 V input. Transmittance, absorbance, concentration, and factor modes cover -0.3 to 3 A, 0 to 200% T, and concentrations up to 9999. Manual wavelength setting keeps colorimetric assays simple, and the unit accepts both glass cuvettes and test tubes for routine concentration checks. Four glass cuvettes, a black block, and a dust cover ship standard, while quartz and micro cuvettes are optional. Food and beverage QC labs check color and ingredient levels, and pharmaceutical teams confirm concentrations in visible-range assays. Environmental labs run colorimetric water tests, chemical plants verify batch strength, and clinical labs perform basic photometry. Teaching labs favor this benchtop spectrophotometer for its low cost and simple keypad. See the Visible Spectrophotometers and Visible Spectrophotometer pages for full specifications.
