Description
EziLab offers the Double Beam UV-Vis Spectrophotometer EZL-DBS105, a benchtop spectrophotometer covering 190 to 1100 nm with 4 bandwidths of 0.5, 1, 2, and 4 nm. Wavelength repeatability holds at 0.1 nm or better, stray light stays at 0.05% T or less, and baseline drift at 0.001 A per hour. Deuterium and tungsten lamps, an automatic cell holder, and a 10-inch touchscreen come standard, with USB or optional Bluetooth output. Narrow 0.5 nm settings resolve closely spaced peaks, while wider 4 nm settings boost light throughput for faster scans, so one double beam spectrophotometer adapts to each method. Sample and reference beams cancel lamp drift during kinetics and multi-point calibration. The automatic cell holder queues samples in sequence, and this UV-Vis spectrometer also quantifies DNA and proteins and runs colorimetric assays. Environmental and quality control laboratories detect pollutants in water and effluent, while pharmaceutical teams use it for method development and drug formulation analysis. Food and beverage testers check color and additives, biotechnology groups run nucleic acid checks, and clinical and academic labs use this lab spectrophotometer for research and teaching. Multi-method labs gain most. See the Double Beam UV-Visible Spectrophotometers and Double Beam UV-Vis Spectrophotometer pages for full specifications.
