Whitehouse Sieve Standards expose inferior mesh

A recent study carried out by Whitehouse Scientific exposed an imported sieve mesh as falling far short of its claimed performance specifications. Since many such meshes are used in critical industrial applications, these findings illustrate the importance of strict checks and calibration using proven methods.

The mesh tested was purchased as a 'precision mesh.' Calibration using the Whitehouse Scientific sieve standards revealed it to be an inferior product compared with its competitors, even though it had the same mesh rating (number of wires per inch). This finding was also confirmed by microscopy.

In practice, the accuracy of Whitehouse Scientific's sieve calibration microspheres allows detection of subtle differences in performance even when microscope analysis might suggest that two different meshes were identical. The technique can be used even on the highest quality electroformed sieves.
