Sieving is the process of separating particles by size. The process started in ancient times in Egypt where sieves were used to separate grain. Today there are high tech methods such as laser diffraction and image analysis used to determine particle size distribution. Other methods such centrifuge techniques and sedimentation are also used. However, sieves are the most commonly used devices for particle size analysis. The sieving process is comparatively inexpensive, simple in concept and easy to use.
Our selection includes frame diameters from 100 millimeters to 18 inches in stainless steel and brass frames.
Sieve mesh material options include stainless steel wire mesh in aperture sizes from 125 millimeters (5 inches) to 20 microns, electroformed openings as small as 2 microns, and perforated plate of various shaped holes.

A mid-point sieve has had the mesh inspected. The sieve is then selected as a mid-point if the results give tolerances that are in the middle of the ASTM standard. The predominant application for mid-point sieves is as master stack.
