General description

Ideal for profiling particle size distribution (PSD) of a particle system.
The particle size of 3 μm is characterized using Coulter multisizer III.

Application

Silicon dioxide beads, 3 μm have a wide range of uses from use as a flow agent to electrical and medical applications.
Used for regular calibration and monitoring of particle size analyzers.
Also used in microfluidic devices to:
  • track flows induced by enzyme micropumps[1]
  • investigate the effects of pumps′ activity on silica tracer microparticles near solid-liquid interface.[2]

Features and Benefits

  • suitable for routine instrument calibration checking, testing and corrections
  • particle size traceable to Community Bureau of Reference (BCR) standards
  • available in 5 mL pack size as a neat sample

Storage Class

10 - Combustible liquids

Micron-sized particles have primarily been used in microfabricated flow cytometers for calibration purposes and proof-of-concept experiments. With increasing frequency, microparticles are serving as a platform for assays measured in these small analytical devices. Light scattering has been used to measure
