Characterising the world’s finest aperture size, square mesh filter

G. Rideal*, K. Brocklehurst, Whitehouse Scientific Ltd, UK

Sieving as a method of particle sizing is not generally regarded as a precision technique however, when accurately calibrated, sieving has consistently outperformed all other Primary Methods of particle sizing when used to certify reference standards.

Although the weaving process is several thousand years old, the basic process has changed little. What has changed is the ability to produce finer wires and weave them to very high tolerances. As a result, fine woven stainless steel meshes are used increasingly as high flow filter and precision classification/separation media.

The world’s finest plain weave mesh is currently made by Asada Mesh (Japan) using 16 micron diameter wires to weave 16 micron apertures. In this report, the Whitehouse Scientific PoreSizerTM has been used to characterise and certify the mesh....
