Description
EziLab offers the Single Beam UV-Vis Spectrophotometer EZL-SBS104, a UV vis spectrometer covering 190 to 1100 nm at a 1.0 nm spectral bandwidth. Wavelength holds within 0.1 nm with repeatability of 0.1 nm or less, photometric readings stay within 0.3% T, and stray light measures 0.05% T at 220 and 360 nm. Deuterium and tungsten lamps feed a silicon photodiode over a thick optical base, drift holds at 0.001 A per 30 minutes, and a 320 by 240 dot LCD with USB and parallel ports completes the unit. That narrow 1.0 nm bandwidth resolves closely spaced spectral peaks that a 2 nm instrument can blur together. Automatic calibration, absorbance, transmittance, and concentration modes, plus bundled PC software for spectral scanning and kinetics, cover routine and method work. Four glass and two quartz cuvettes ship standard, micro cuvettes optional. Pharmaceutical QC labs confirm raw material identity and assay results, while food testing labs analyze chemical composition and additives. Environmental labs measure water parameters, life science groups quantify DNA and proteins, and universities teach with this UV spectrophotometer. Its 110 or 220 V input suits US benches. See the Single Beam UV-Visible Spectrophotometers and Single Beam UV-Vis Spectrophotometer pages for full specifications.
