Product Description UV7600 Double Beam UV-Vis Spectrophotometer Wavelength Range 190nm~1100nmThe double-beam ultraviolet-visible spectrophotometer is a high-performance laboratory optical analyzer, featuring an advanced beam-splitting system that splits the light source into two beams: one passes through the sample cell (test solution), and the other through the reference cell (blank solvent). Both beams alternately illuminate the same high-sensitivity detector for consistent detection.Product DescriptionWith a dual-channel design, the radiation source's light is split into two paths: one through the reference cell (to set a baseline) and the other through the sample cell (for measurement), minimizing external interference and ensuring reliable data.Working PrincipleThe operation of the double-beam ultraviolet-visible spectrophotometer follows a clear, four-step process based on optical absorption principles:Radiation Source GenerationA high-quality radiation source-characterized by stability, monochromaticity, and collimation-emits electromagnetic waves within the visible or ultraviolet wavelength range. This provides a consistent and pure light foundation for subsequent measurements.Beam Splitting & Path TransmissionThe incident light from the radiation source is divided into two parallel paths by a precision beam splitter:Reference Path: One beam passes through the reference cell (blank solution), which contains no target substance and does not interact with the material to be tested.Sample Path: The other beam travels through the sample cell, where it interacts with the target substance (e.g., the substance absorbs specific wavelengths of light) before proceeding to the detector.Signal Detection & ConversionA high-sensitivity detector receives the light signals from both the sample path and the reference path. It then converts these optical signals into electrical signals, which are easier to process and analyze.Data Calculation & Result OutputThe instrument's signal processing system compares the intensity differences between the two electrical signals (from the sample and reference paths). Based on the Lambert-Beer law- a fundamental principle in spectrophotometry-it calculates the degree of absorption or transmission of the incident light by the sample at different wavelengths. Finally, the measurement results (e.g., absorbance, transmittance) are displayed or output for further analysis.Our Advantages1. Real-Time, Rapid AnalysisThe instrument enables real-time and rapid acquisition of key optical parameters-including the absorbance and transmittance of substances in solutions-across different wavelengths. This speeds up experimental processes such as substance concentration analysis and reaction kinetics research, significantly improving laboratory work efficiency.2. Flexible Parameter AdjustmentTo meet the diverse needs of different samples and experiments, the wavelength range and resolution of the spectrophotometer are fully adjustable. This flexibility allows it to adapt to a wide range of applications, from basic chemical analysis to advanced material research.3. High Precision & RepeatabilityEquipped with high-quality core components and a rigorous calibration system, the instrument delivers exceptional precision and repeatability. Even in repeated tests, it minimizes data deviation, ensuring that every measurement result is accurate, reliable, and trustworthy for scientific research or industrial quality control.4. Core Advantage: Double-Beam DesignThe most significant advantage of this spectrophotometer lies in its double-beam structure. This design directly eliminates the adverse effects of light source fluctuations and detector drift-common issues in single-beam instruments-thereby greatly improving measurement accuracy and long-term stability. It is particularly suitable for long-duration continuous tests and high-precision analytical tasks.Application FieldsThis double-beam ultraviolet-visible spectrophotometer is a versatile analytical tool widely used in:Chemical Industry: Solution concentration determination, chemical substance identification, reaction kinetics monitoring.Pharmaceutical Industry: Drug content analysis, purity testing of pharmaceutical raw materials, quality control of finished products.Environmental Protection: Detection of harmful substances in water/air samples, analysis of pollutant concentrations.Food Industry: Measurement of food additive content, nutrient analysis (e.g., vitamin content), quality safety testing.Scientific Research Institutions: Experimental research in chemistry, biology, materials science, environmental science, and other disciplines.Whether for scientific research, industrial quality control, or laboratory teaching, this instrument provides reliable, efficient, and high-precision analytical solutions to support your work.Product ParametersTechnical Parameters:ModelUV7600/UV1910/UV1920Optical SystemOptical Double-BeamWavelength Range190nm~1100nmSpectral Bandwidth0.5nm~6nm continuously variable (0.1nm intervals)Baseline Straightness±0.0008ALight SourceJapanese Hamamatsu long-life lamp, imported long-life halogen tungsten lampDetectorImported silicon photocellDisplay7-inch large-screen color touch LCDDetailed Photos
