Description

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

Used for regular calibration and monitoring of particle size analyzers.
Also used in microfluidic devices to:

track flows induced by enzyme micropumps
investigate the effects of pumps′ activity on silica tracer microparticles near solid-liquid interface.

Silicon dioxide beads, 3 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 checking, testing and corrections
particle size traceable to Community Bureau of Reference (BCR) standards
available in 5 mL pack size as a neat sample
