|NIST Traceable Particle Size Standard, Diameter 4μm
Particle size standards may be used to validate sizing instruments across their dynamic ranges. They are suitable for use in the performance of routine instrument calibration checks and corrections, and in the support of practice standards, such as those published by ISO, ASTM International, CEN, and other organizations. Additionally, the use of reference material permits the standardization of results between runs, instruments, laboratories, and over time. Bangs NIST Traceable Particle Size Standards are monodisperse polystyrene spheres available in diameters ranging from 40nm-175μm. Suspensions are conveniently packaged in dropper bottles at 1% solids (w/v) in de-ionized water with surfactant, and each bottle is provided with a Certificate of Traceability. :
