Product Description 759S Portable Laboratory Ultraviolet-Vis Spectrophotometer Single Beam UR-VIS SpectrophotometerProduct Description759S Spectrophotometer is a UV-VIS spectrophotometer. The instrument has features like a delicate structure, high-performance specification, long-life light source, various convenient functions, etc. They could make qualitative and quantitative tests in material research, pharmaceutical analysis, Biochemical and clinical examination, analysis of water quality control, food inspection, and other fields. Structure:The UV-Visible Spectrophotometer primarily consists of five main parts: a light source, a monochromator, a sample cell, a detector, and a data processing system.Light Source: It includes both ultraviolet and visible light sources, capable of emitting a continuous spectrum within the range of 190-1100nm.Monochromator: An optical component used to select light of a specific wavelength.Sample Cell: Used for placing the sample to be tested, typically made of quartz or glass.Detector: Monitors the intensity of light after it passes through the sample.Data Processing System: Records and processes the signals received by the detector to obtain the absorbance value of the sample. Product FeaturesLong-life Light Source: Dramatically reduces the cost of light source replacement and the frequency of maintenance.Low Stray Light: Ensures stray light is lower than 0.05% (756S: 0.1%) to meet clients' needs for testing high absorbance samples.High Wavelength Accuracy: Ensures accuracy and long-term stability.Wide Wavelength Range: Meets the needs of most spectrophotometric tests.High-speed Scanning: Helps users capture the instantaneous spectrum change of samples and improves work efficiency.Auto-matching Function of Cuvettes: Reduces deviations caused by differences in cuvettes during batch measurement.High Photometric Accuracy: Ensures the measurement of the optical path meets design requirements, improves the assembly process efficiency, and achieves high-precision photometric testing indicators.Flash Disk Storage: Facilitates users to manage data in formats such as Excel.USB Ports: Users do not need to set any parameters to enable online communication, while the RS232 serial port requires parameter setting.Various Offline Quantitative Measurement Functions: The electronic system adopts a 32-bit ARM core processor and is equipped with a 128*64 large-screen LCD. Offline quantitative measurement can perform multi-wavelength testing, standard curve fitting and measurement, standard coefficient equation input, standard equation saving and loading, data storage and printing, and concentration quantitative measurement.Powerful Software Function: The software can realize spectrum scanning, time scanning, dynamic scanning, quantitative measurement, multi-wavelength analysis and formula calculation, spectrum processing, peak and valley finding, data printing, DNA/RNA testing, instrument calibration, performance verification, etc., to meet different needs in various analysis fields.Product ParametersTechnical Parameters:Standard Configuration:Optional Accessories: Working Principle of Ultraviolet-Visible SpectrophotometerA radiation source with stability, monochromaticity, and collimation generates electromagnetic waves within the ultraviolet and visible ranges.The incident light is split into two beams by a divider one passes through the reference cell (blank), and the other passes through the sample cell for measurement.Based on the intensity differences between the incident and outgoing light at different wavelengths, the degree of absorption or transmission of the incident light by the sample at that wavelength can be determined.The detector receives the signals returned from the sample and reference cells and converts them into electrical signals.Features and Advantages of Ultraviolet-Visible SpectrophotometerCapable of obtaining absorption spectra of substances in solution at different wavelengths, providing information on chemical structure and the concentration of components in the solution.Adjustable wavelength range with high precision, suitable for different types of samples and experimental needs.Capable of performing quantitative analysis to measure the concentration of components in a solution.Provides fast, accurate, and reliable measurement results.Application ScopeThe Ultraviolet-Visible Spectrophotometer (UV-Vis Spectrophotometer) is a commonly used laboratory instrument for measuring the absorption and transmission characteristics of samples within the ultraviolet and visible ranges of electromagnetic radiation.Technical ParametersParameterValueInstrument ModelAT61084Optical SystemDiffraction Grating C-T MonochromatorLight SourceJapanese Hamamatsu Long-Life High-Stability Lamp (2000 hours), Long-Life Tungsten LampWavelength Range190nm ~ 1100nmWavelength Accuracy±0.5nmWavelength Repeatability≤0.2nmBandwidth2nmTransmittance Accuracy±0.3%TTransmittance Repeatability≤0.15%TStray Light≤0.05%T (220nm, NaI)Baseline Flatness±0.002ADrift≤0.0008ANoise≤0.3%T (100%T), ≤0.1%T (0%T)Photometric Range0.0 ~ 200% (T), -0.3 ~ 4 (A)Display System128×64 Large-Screen LCD DisplayHost Interface FunctionsUSB-A (U Disk), USB-B (Online Connection), Serial Port (Printer)Instrument Dimensions370mm × 440mm × 220mm (370mm × 357mm × 220mm)Weight9kgDetailed Photos
