Description
EziLab's Double Beam UV-Vis Spectrophotometer EZL-DBS100 scans 190 to 1100 nm at a fixed 1.8 nm bandwidth, using a double beam optical system with a 1200 lines/mm grating and tungsten and deuterium lamps for stable readings across the full range. Automatic calibration, a high-stability optical design holding drift below 0.0005 A per hour, and a 320x240 dot LCD display keep routine absorbance work consistent from one session to the next, while USB and parallel port outputs move data into lab software without manual transcription. Stray light stays below 0.03% T at 220 nm and 360 nm, giving this uv vis spectrometer steady low-end performance for trace work. Pharmaceutical quality control labs use it for raw material and finished-product absorbance checks, while biochemical testing labs run protein and enzyme assays on the same vis spectrophotometer platform. Food industry laboratories apply the same double beam spectrophotometer to colorimetric and additive analysis, and routine absorbance measurement work across academic and contract labs benefits from the bench-top footprint. Quality control departments running high sample counts favor a uv spectrophotometer of this stability to keep recalibration infrequent. See the Double Beam UV-Vis Spectrophotometers and Double Beam UV-Vis Spectrophotometer pages for further specifications and ordering details.
