Single Size Glass Beads

Single size glass beads are offered in a 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 analyzers 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.
