STANDARDS FOR 100mm DIAMETER SIEVES
5 bottle set, 0.25g per bottle.

Named after the Primary Sieve Size (38um)
but also suitable for 36um & 40um Sieves

  • Unique microsphere method of sieve calibration
  • Mean aperture sizes traceable to NIST and NPL
  • Measure over 1 million apertures per minute
  • Typical calibration time of about 1 minute
  • Method analyses over 80% of the sieve surface
  • Accuracies and repeatabilities better than 1µm 
  • Results independent of sieve shaking method
  • Single-shot bottles remove operator bias
  • No need to send sieves away for calibration
Quick and simple to use!
Empty the complete contents of a bottle onto the sieve and shake evenly over the surface for 1 minute. Calculate the percentage passing and read off the mean aperture size from the calibration graph.
