NIST Traceable Size Standards
Microspheres & Particles
Microbead NIST Traceable Particle Size Standards A2dm
Microbead NIST Traceable Particle Size Standards are monodisperse polystyrene microspheres ranging
from 1.0µm to 9.0µm. They are packaged in convenient, easy-to-use 15ml dropper bottles at
1% solids (w/v) in an aqueous suspension.
