Introduction: UV1910 dual-beam UV-Vis spectrophotometer is a high-performance photometer product developed by our company with 25 years of experience in research and development of spectrometers. The product has the characteristics of high resolution, high stability, flexibility and ease of use, which can meet the daily analysis of various laboratories, research and analysis of scientific research institutes and other various needs. Features: 1. Ultra-low stray light: The excellent C-T monochromator optical system and advanced electronics system ensure an ultra-low stray light level better than 0.03% to meet the user's measurement requirements for samples with high absorbance. 2. High-quality components: The core components are all imported high-quality components to ensure the stability, reliability and long life of the instrument. For example, the core light source device is derived from the long-life deuterium lamp of HAMAMATSU, Japan, which guarantees a working life of more than 2000 hours, which greatly reduces the maintenance frequency and cost of the instrument's daily replacement of the light source. 3. Long-term stability and reliability: The optical dual-beam optical system design, combined with real-time digital proportional feedback signal processing, effectively offsets the signal drift of the light source and other components, and ensures the long-term stability of the instrument baseline. 4. High wavelength accuracy: The high-level wavelength scanning mechanical system guarantees wavelength accuracy better than 0.3nm and wavelength repeatability better than 0.1nm. The instrument uses the built-in spectral characteristic wavelength to automatically perform wavelength detection and correction to ensure wavelength accuracy. Long-term stability. 5. Convenient light source replacement: the instrument can replace the light source without removing the casing. The light source switching mirror supports the function of automatically finding the best position. The design of the in-line deuterium lamp tungsten lamp does not require optical debugging when maintaining and replacing the light source. 6. Rich stand-alone function: stand-alone is equipped with a 7-inch large-screen color touch LCD screen, which can perform wavelength scanning, time scanning, multi-wavelength analysis, quantitative analysis, etc., and supports method and data file storage. The files can be stored in a U disk. Computer to view and print the map. Simple to use, flexible and efficient. 7. Powerful online software: the instrument is connected to the computer via USB. The online software supports wavelength scanning, time scanning, kinetic testing, quantitative analysis, multi-wavelength analysis, DNA/RNA analysis, instrument calibration, performance verification and other functions. Support user authority management, operation traceability function, to meet the various requirements of different analytical fields such as pharmaceutical companies. 8. Abundant accessory support: The instrument can be equipped with 6-cell or 8-cell automatic sample holder, and supports cuvettes with optical path length from 1mm to 100mm Specifications, support the spectrum test of various sample forms such as film samples.
