Calibrate your sieve in 2 minutes! New Whitehouse Scientific video explains how

Whitehouse Scientific Sieve Calibration videoA new two-minute video freely accessible on the Whitehouse Scientific website takes viewers through the complete methodology for calibrating a test sieve using the Whitehouse Scientific glass bead method. The clear visual demonstration and concise verbal instructions are designed to help newcomers to the method or to act as a refresher for existing users. Access to the video is via the ‘sieve standards' pages of  where visitors can also download written instructions. 

Whitehouse Scientific's NIST Traceable Sieve Standards are narrow distribution glass microspheres that enable the on-site calibration of sieves from 20 to 3350 µm.  Accurate to 1 µm for smaller sieve apertures, these standards allow complete calibration in around two minutes and the results are independent of the sieve shaking method used. Furthermore, single shot bottles remove operator sampling errors, making the entire process more reliable and reproducible. 

Full details of which standards to select for a particular sieve type and size, together with further background information, are available on the website at
