Precision Size Standards are offered in three size groupings: Nanobead, Microbead, and Megabead. They are measured on in-house instruments calibrated with NIST (National Institute of Standards and Technology) Standard Reference Materials. Each product is supplied with a Certificate of Analysis documenting traceability to NIST Standard Reference Materials. The size, standard deviation, coefficient of variation, and lot number are printed on the label for easy reference.

Nanobead NIST Traceable Particle Size Standards are monodisperse polystyrene microspheres ranging from 40nm to 950nm. They are packaged in convenient, easy to use 15ml dropper bottles at 1% solids (w/v) in an aqueous suspension.

Nominal Diameter: 60nm
