Polydisperse Particle Standards

The Polydisperse Particle Standards were formally known as the BCR 'Mirror' Standards because they mirrored the size ranges of an official set of spherical reference standards that were being developed for the European Community (Community Bureau of Reference - BCR).

Opaque Polydisperse Standards

Most particle size reference standards are transparent in nature including glass and latex microspheres However in some optically based particle

Monodisperse Standards

Ultra-narrow size distribution glass microspheresOnly a few microns separating many gradesTraceable to international standards - NIST NPLThe widest

Sieve Standards
