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.
