Features

  • 10.1 inches high resolution TFT colored capacitive touch screen and windows graphic interface.
  • Powerful functions like Photometric measurement, Quantitative measurement, Kinetics, Spectrum scan, DNA\Protein test, multi-wavelength test, etc
  • In-house massive memory is capable of saving up to 1024M for test data & working curves.
  • Supports USB & SD card storage. The USB port can be used for data transfer, which is easily exported to Excel for further processing, analysis and storage.
  • Socket type deuterium and tungsten lamp can make lamps switching without optics debugging and easy to be replaced.
  • Large sample chamber can accommodate 5-100mm cuvettes of all kinds.
  • Extensive accessories are optional, such as auto 8-cell holder, film holder, peltier/sipper system, 21 CFR compliant software, built-in printer, etc.
