  • High-quality components: The core components are 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 (HAMAMATSU) in Japan, which guarantees a working life of more than 2000 hours and greatly reduces the maintenance frequency and cost of daily replacement of the light source of the instrument.

    Long-term stability and reliability: The optical double-beam optical system design, combined with real-time digital proportional feedback signal processing, effectively offsets the signal drift of the light source and other devices, and ensures the long-term stability of the instrument baseline.

    Light source replacement is convenient: 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, and the in-line deuterium lamp tungsten lamp design requires no optical debugging when maintaining and replacing the light source.

    Rich stand-alone functions: The stand-alone machine 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. View and print maps. Easy to use, flexible and efficient.

    Rich accessory support: The instrument can be configured with 6-cell or 8-cell automatic sample racks, supports cuvettes with optical path lengths from 1mm to 100mm, and supports spectral testing of various sample forms such as film samples.

  • UV1910 dual-beam UV-Vis spectrophotometer is a high-performance photometer product developed by Shanghai Prism Technology Co., Ltd. The product has the characteristics of high resolution, high stability, flexibility and ease of use, which can meet various needs of daily analysis in various laboratories, research and analysis in scientific research institutes, etc.
