Product Description

Product Introduction

UV Visible Spectrophotometer UV-720 is a high-performance spectrophotometer designed for various quantitative analyses of substances using spectral analysis methods in modern analytical laboratories. It is widely used in pharmaceuticals, environmental protection, food industry, petrochemicals, biochemistry, universities, and quality control departments.


Product Features
1. Employs a high-performance grating with 1200 lines/mm. A new light source control system enables faster light source switching.
2. Precise 2nm bandwidth ensures more accurate test data. Uses imported long-life light sources, reducing consumable consumption.
3. Unique wavelength control system for higher wavelength accuracy. Improved optical system for more accurate testing.
4. Uses imported photoelectric converters for higher instrument sensitivity.
5. New microcomputer data processing system. Makes the instrument more convenient to use and more stable.
6. The instrument uses a 126×64 dot-matrix LCD display, which can directly display standard curves and test data. The main unit can store test data, and a printer is optional.
7. The instrument can be equipped with a patented rotary automatic eight-piece sample holder, offering high reliability and centered light spot (compared to a double-row automatic eight-piece holder), resulting in higher photometric accuracy.

UV Visible Spectrophotometer Functions

1. Automatically saves the latest wavelength based on the set wavelength.
2. Increased measurement stability compared to similar products.
3. Measurable optical path length: 100mm.
4. Establishes quantitative analysis modes based on standard mode or by inputting a standard mode.
5. Capable of saving 200 calibration curves.
6. Optional software for computer connection is available.
