General description

Silicon dioxide based microparticles (size: 0.15 μm) are ideal to determine particle size distribution (PSD) profile of a particle system.
The particle size of 0.15 μm is characterized using CPS disc centrifuge DC24000.

Application

Used for regular calibration and checking of particle size instruments. Also used to produce microporous graphene assemblies.
Silicon dioxide beads, 0.15 μm have a wide range of uses from use as a flow agent to electrical and medical applications.

Features and Benefits

  • suitable for routine instrument calibration monitoring, testing and corrections
  • particle size traceable to NIST and SRM standards
  • available in 5 mL pack size as a neat sample
