Duke Standard 8000 Series Silica Particle Size Standards


Provide greater durability and chemical stability when using solvents with Thermo Scientific™ 8000 Series Silica Particle Size Standards, monodisperse silica microspheres used in instrument calibration and as spacers. Standards are calibrated and certified with NIST™ traceable mean diameters and are suitable for a wide variety of particle measurement applications.


  • Standards are designed for applications requiring monodisperse inorganic spheres.
  • Opaque spheres provide more contrast than polymer particles in optical and electron beams; like glass, silica has a much higher density that polystyrene.
