Product details
19 series UV visible spectrophotometerThe TU-1901/1900 series UV visible spectrophotometer has been widely used in scientific research and production in various fields such as organic chemistry, biochemistry, drug analysis, food inspection, medicine and health, environmental protection, and life sciences.
19 series UV visible spectrophotometermain features
Strong instrument performance: extremely excellent optical system, advanced electronic system, high-level mechanical system, ensuring ultra-low stray light of 0.010% T.
Stable and reliable quality: The dual beam dynamic feedback proportional recording metering system ensures baseline stability.
Key components such as deuterium lamps and photomultiplier tubes are imported to ensure the stability, reliability, and long lifespan of the instrument.
Accurate measurement: Using imported high-quality holographic gratings, further reducing the instrument's stray light and making the instrument analysis more accurate.
Easy and efficient human-machine dialogue: UVWin Chinese operating software designed based on the Windows environment provides rich instrument control and operation functions, simple and easy to use, flexible and efficient, and easily meets the analysis needs of users.
Excellent scalability: There are a large number of user selectable accessories such as peristaltic sampler, ultra micro cell holder, constant temperature cell holder, optical integrating sphere, mirror reflection, fiber optic accessories, and colorimetric dish series, greatly expanding the application range of the instrument.
Equipment maintenance is simple and convenient: * The socket type tungsten lamp and deuterium lamp eliminate optical debugging when replacing the lamp, making equipment and instrument debugging and maintenance easier and more convenient.
Powerful and convenient software analysis assistant - UVWin5.0
Advanced Windows multi document interface, UVWin5.0 control software, capable of displaying multiple modes simultaneously and switching measurement methods instantly. The main interface provides all functions and is the foundation for users to operate the software. Including: menu, tool buttons, measurement module, status information, etc.
Four major conventional measurement functions
Photometric measurement, quantitative determination, spectral scanning, time scanning
◇ Three dimensional spectrum function
Provide the function of combining multiple measured spectral curves into three-dimensional graphics for display, editing, and printing.
◇ DNA/protein assay function
Users can use this feature to measure the concentration of DNA/protein, and also set different analysis methods to meet different needs.
The software follows GLP standards
Multi user management: allows administrators to create users and groups with different permissions; Each user needs to enter their corresponding account and password when logging into the software; The protection function of measurement data can be implemented for general users.
Logging function: Automatically record user actions; The log files are saved in a more reliable database format; Administrators can categorize and review logs for other processing purposes.
Binary file saving: The measurement data is saved in binary format; The binary format greatly enhances the confidentiality of data; It also saves disk space.
Quality control function: can monitor measurement data according to user settings; Data systems that exceed the control range will display prompt messages, perform color labeling, or automatically remeasure.
Report output function: capable of sharing data with other systems; The measurement results can be saved in Microsoft Word format, Microsoft Excel format, or text file format; Personalized settings can be made for the report format; You can preview the printing effect of the result report in advance.
