Diffractometer | APD 2000 PRO
€1,000,000.00

Overview

APD 2000 PRO diffractometer is an high power - Theta/2Theta - laboratory powder X-Ray Diffractometer equipped with all the most moder technical features which grant accuracy, precision, safety and easiness of use for XRD analysis of polycrystalline materials. 

Thanks to a wide offer of configurations and accessories such as high-speed detector, scintillation counter, high-low temperature and humiduty chamber, secondary monochromator, spinner and multiple sample holder, APD 2000 PRO is a powerful tool for powder diffraction applications such as routinary qualitative and quantitative phase analysis, non-ambient analysis, structure solution and refinement, crystallite size and degree of crystallinity calculation. 

  • High Speed Rate (1000°/min) 
  • High Precision Angle Reproducibility (+/- 0.0001°) 
  • Fast Measurement and Highly Reliable Data 
  • Extremely precise angular values thanks to stepper motors with optical encoders 
  • Easy to handle
