EziLab offers the Double Beam UV-Vis Spectrophotometer EZL-DBS103, a benchtop spectrophotometer covering 190 to 1100 nm at a fixed 1.8 nm bandwidth. Deuterium and tungsten lamps feed a fine-pitch grating, holding wavelength repeatability at 0.1 nm or better, stray light at 0.05% T or less, and baseline drift at 0.001 A per hour. Automatic wavelength calibration and a 10-inch touchscreen handle setup, and results export by USB or optional Bluetooth. The double beam spectrophotometer reads sample and reference at once, so lamp drift cancels during long kinetic runs and QC checks. Photometric range spans -0.3 to 3 Abs, 0 to 200% T, and direct concentration readout, and the touchscreen switches between scanning, quantitation, and kinetics. As a UV spectrophotometer it quantifies nucleic acids and proteins, and supplied glass and quartz cuvettes cover visible and UV work. Pharmaceutical QC labs check assay and drug release samples, while chemical and beverage producers run concentration and color checks on each batch. Environmental labs measure nutrients and contaminants in water, and university teaching labs use this lab spectrophotometer for method training. Dual 110 or 220 V input suits US sites. If your data system reads only USB files, skip the optional Bluetooth link and shortlist from the Spectrophotometer category and Double Beam UV-Visible Spectrophotometer range.

The Double Beam UV-Vis Spectrophotometer EZL-DBS103 is classified as a double-beam spectrophotometer because it splits the light beam into two paths: one passing through the sample and the other through a reference. This simultaneous measurement allows for better baseline stability, minimizes the effect of light source fluctuations, and enhances long-term measurement accuracy. It is especially useful in applications that require consistent and reliable absorbance readings over extended periods, such as kinetic studies or routine quality control testing.
Ezilab’s Double Beam UV-Vis Spectrophotometer EZL-DBS103 is used in a wide range of applications, including pharmaceutical analysis, chemical testing, environmental monitoring, food and beverage quality control, and biological research. It can measure absorbance, transmittance, concentration, and perform wavelength scanning. Its ability to deliver accurate, reproducible data makes it ideal for detecting contaminants, analyzing formulations, quantifying nucleic acids and proteins, and verifying product consistency in regulated environments like GMP or academic research labs.
Our Double Beam UV-Vis Spectrophotometer EZL-DBS103 ensures high accuracy through its double-beam configuration, precision optical grating, and wide wavelength range of 190 to 1100 nm.
