    Features

    • UV VIS spectrophotometers adopt split beam survey optical system, and blazed holographic gratings with outstanding test precision and very competitive prices.
    • 7-inch color touch screen LCD display, cutting-edge user interface, powerful functions, and easy operation.
    • The automated eight-position cuvettes holder facilitates the operation under each measurement mode.
    • Great performance in qualitative and quantitative testing, with powerful functions such as: full-spectrum scanning (optional),detailed spectrum scanning, time-based kinetics determination, linear regression, concentration direct reading, Peak/Valley detecting, multi-wavelength measurement etc.
    • Designed with sophisticated power protection system. With high capacity of internal memory, it can store testing results, scanned images, regression equations and correction data. Therefore, it follows a fast initialization when power on.
    • UV and Visible spectrophotometer can be connected with dedicated printer, which can print testing results, or draw curve from spectral scanning, fixed wavelength time-based scanning, and linear regression.

    Tips: What is a spectrophotometer?
    Spectrophotometry is the absorption of light at a specific wavelength or within a range of wavelengths for qualitative or quantitative analysis of the material. The commonly used wavelength ranges are: 200-380nm UV spectrum, 380-780nm visible spectrum, 2.5-25μmInfrared spectrum. The instruments used for testing these spectrums are ultraviolet spectrophotometers, visible spectrophotometers (or colorimeter), infrared spectrophotometers, or atomic absorption spectrophotometers.
    Spectrophotometers have become conventional instruments in modern molecular biology laboratories. It is commonly used for quantification of nucleic acids, protein quantification, and bacterial growth concentrations.
    The spectrophotometer instrument consists of a light source, a monochromator, a sample chamber, a detector, a signal processor, and a display and storage system.
    Different light sources have their own emission spectra, so different light emitters can be used as light sources for the instrument.

    • Tungsten Emission Spectroscopy
      Tungsten light emits a spectrum of 400-760nm wavelength, which is refracted by a triangular prism and generates continuous chromatograms consisting of red orange, yellow-green, blue-violet, and violet. The spectrum can be used as a visible spectrophotometer light source.
    • Emission spectroscopy of Hydrogen (or Xenon) lamps
      Hydrogen or Xenon lamps emit wavelengths in the range of 185 to 400 nm and can be used as light sources for ultraviolet photometers.
