Our ISO Sieves are available with stainless steel frames and mesh, or brass frames with stainless steel mesh in full height or half height sizes. High-quality all-stainless steel sieves offer long service life and reduce specimen contamination. ISO Test sieves are available with full height or half height frames. Half height frames allow more sieves to be used in a stack. Stainless steel Backing Cloth with 500µm openings is available to reinforce 200mm or 300mm ISO Test Sieves with primary cloth 212µm and finer. Backing Cloth means the Test Sieve will last longer and avoids issues with sagging and distortion of the mesh.

Sample volume and particle size determine proper frame diameter and height. Material is processed more efficiently and accurately on a sieve with more surface area, and blinding is reduced. The thickness of a specimen fraction on the mesh of a sieve should be no more than a couple of particles or layers deep. Frame height must permit proper agitation of the specimen, allowing larger particles enough room to reorient to the mesh surface.

Gilson ISO Compliance sieves are supplied with a serial number and Compliance certificate. The certificates do not verify measurements of an individual sieve, but that the wire cloth and manufacturing methods comply with ISO requirements. Inspection (99.0% confidence) or Calibration (99.73% confidence) Services individually measure sieves, and these services can be added to increase confidence that sieve meet ISO standards.
