Glass Microspheres are traceable to NIST standards.

Press Release Summary:

Comprised of single size glass beads greater than 1 mm in diameter, Monodisperse Standards have narrow particle size distributions and come in sets of 5 single shot bottles from 0.1-1.0 g. These reference calibration beads come with NIST-traceable test certificate and suit application areas such as pharmaceuticals, foodstuffs, polymers, and specialty chemicals.

Whitehouse Scientific Extends the Range of Single Size Glass Beads

Whitehouse Scientific has responded to an increased interest in automated measurement of large particle sizes by introducing single size glass beads of greater than 1 mm in diameter.

Traditionally, sieve analysis has been used for such large sizes, which are also near the upper limit of some laser diffraction methods of analysis. As image analysers now have a firm foothold in this sector, there is a requirement for NIST traceable reference calibration beads.

The Monodisperse Standards have very narrow particle size distributions and come in sets of five single shot bottles, together with a NIST traceable test certificate. Application areas include pharmaceuticals, foodstuffs, polymers and speciality chemicals. For full details visit
