Product Description

756S UV VIS Spectrophotometer High Performance Single Beam 190-1100nm

756S 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 Features

Long-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.
