Supplied in sets of 5 single shot bottles, each shot is suitable for one calibration test, thereby avoiding operator error. These provide a quick and economical method of calibrating sieves.

These Sieve Calibration Beads are manufactured from soda-lime glass and certified using NIST & NPL traceable electroformed sieves. They are accurate to 1 micron for the smaller aperture sieves and are supplied with a certificate of analysis.
