Description
EziLab Double Beam UV-Vis Spectrophotometer EZL-DBS101 performs absorbance, transmittance, and concentration measurements across pharmaceutical analysis, environmental monitoring, food quality testing, and chemical laboratory applications. Wavelength range spans 190 to 1100 nm with 1 nm spectral bandwidth and 0.1 nm accuracy for precise lab spectrophotometer performance. Double beam optical system with 1200 lines per mm grating and dual tungsten and deuterium lamp illumination ensures consistent signal quality, while stability stays within 0.0005 A per hour. Stray light remains below 0.03% T at 220 and 360 nm, with USB and parallel port output for streamlined data handling across routine workflows. EziLab's Lab Equipment and spectrophotometers list the complete lab spectrophotometer and double beam UV-Vis analysis range.
