0.1-5nm Double Beam UV-Vis Spectrophotometer LCD Screen

0.1-5nm Double Beam UV-Vis Spectrophotometer LCD Screen

A spectrophotometer is commonly used for the measurement of transmittance or reflectance of solutions, transparent or opaque solids, such as polished glass, or gases. In chemistry, spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.

This series of products is based on the years of spectral instrument design and manufacturing experience of LABOAO. It has newly developed a series of double-beam UV-Vis spectrophotometers. The new optical path design, sensitive photomultiplier tube receiver, cross-national procurement of preferred accessories, superior instrument performance, and greatly meet the analytical needs of the most professional users. It can be widely used in scientific research and production in various fields such as organic chemistry, biochemistry, pharmaceutical analysis, food inspection, medical and health, environmental protection, and life sciences.

The instrument uses pulsed xenon lamp as the light source. The instrument is used normally for at least 7 years, no need to replace the light source, and the user's instrument use cost is minimized. We use original optical, circuit, structural design, advanced process specifications and strict quality management system to create this international advanced level, to meet user needs and usage habits. Microcomputer control and processing data, large-screen color display, graphical interface operation and user-friendly menu prompts, ready to draw spectral maps and analyze test data. It has many functions such as photometric measurement, automatic scanning measurement spectrum, quantitative analysis, and dynamic spectrophotometry. The sensitivity and accuracy of the analysis are high; the spectral data processing function is strong; the Chinese man-machine dialogue is convenient, the operation is convenient; the appearance of the instrument is beautiful and generous.


1. 10.1-inch color touch screen display, large screen display directly displays a variety of scan curves and maps, allowing users to complete all measurement needs without the aid of a computer.

2. Support U disk storage, convenient for users to use, user measured data can be directly exported to U disk, data opening and editing does not require any professional auxiliary software support, can support excel, txt format, image format (can output four formats : *.csv, *.qua.*.tet, *.bmp), it is convenient for users to edit the experiment report directly on the PC, which greatly saves the experimental table space and is convenient for users.

3. Data output: RS-232C serial port (printing), USB drive (online), USB HOST (connected to U disk), standard 16GB memory.

4. The industry's first to use the advanced ARM12 processor, the instrument can store 5000 test data or 500 work curves.

5. Suspension optical system design, strengthen the thick aluminum base plate design, eliminate the impact of vibration or deformation on the optical system; double-layer design, completely separate the optical circuit parts, even if the instrument is maintained, the fork avoids light and electricity. Mutual interference increases the resolution and stability of the instrument.

6. The instrument adopts the national patent ZL 2010 2 0562320.3 photoelectric signal detection device to make the instrument signal-to-noise ratio lower and the instrument more stable.
