UV-VIS SPECTROSCOPY

Be updated : 24-10-2016 09:06:38

Model: Jasco V630 –Japan

Spectrophotometer UV - VIS operates on the basis of measuring the light absorption characteristics as well as optical transmission at different wavelengths, the results are obtained quickly and accurately. Particularly, this is used widely in beverage industry to determine the trace elements as well as the targets of food safety. Additionally, the machine can also be used for colorimetric analysis of heavy metals such as Cr, As, Zn, Al, Hg ...

  1.  
  • Easy to use software: Measure the absorbance, transmittance or optical measurement of the concentration with the concentration factor or factors such as concentration standards µg / ml, mg / ml, g / l, ppb, ppm,%, IU, mM / l, M / l or other concentration values ​​can be inserted by the keyboard, display continuously measured values ​​without rodent reading keys.
  • There are adjustable quantitative and scanning functions that universally bring high efficiency and high accuracy
  • There are concentration and purity calculating function for DNA / protein
  • There are multi-wavelength measurement functions.
