Project Description

EPRUI Biotech supplies three different matrixes of particle size standards: Polystyrene, PMMA and Silica. The particle size ranges from 100nm to 50um.

We supplies a full range of size standard microspheres based on patented particle technology. All of our particles standards are determined by Coulter Counter, DPS Disk Centrifuge, Dynamic Light Scattering, TEM, SEM, and Optical Microscope against Standard Reference Materials (SRMs) from the National Institute of Standards and Technology, U.S. Department of Commerce (NIST).  The particle sizes of these microspheres are therefore traceable to globally recognized primary standards of NIST SRMs.

All particle size standards supplied from EPRUI are either cross-linked polymer or silica microspheres.  The polymer particle size standards >1um in diameter are based on highly crosslinked polystyrene or poly(methyl methacrylate) for improved physical and chemical stability.
