Wet-Wash & Geological Sieves for Fines Testing
Match the Sieve to the Wet-Washing Method
Wet-wash sieving separates fines from a sample by washing them through the screen with water. Choose a sieve whose frame is deep enough to hold wash water above the cloth, and confirm the openings required by the procedure. Sample recovery and the required opening series are the first selection criteria.
One listed configuration is the 3in brass/stainless wet-wash sieve, 4in deep, No. 100. Its listing identifies ASTM E11 compliance, a conformance certificate and 4in frame depth. Those details belong to that configuration; check each listing rather than assuming the entire category shares the same standard list.
Choose Diameter, Depth and Backing Cloth
Select frame diameter to suit sample size and existing pans, covers and shakers. Deep frames contain wash water; the example above states a 4in depth above the cloth. Compare available diameters and frame constructions on each listing before ordering.
Backing support cloth is a separate option: the category lists a No. 100 version with backing cloth alongside the version without. Confirm which configuration the procedure expects rather than treating backing cloth as a default inclusion.
Select Replacement Screens and Accessories
Where an existing frame uses replaceable media, match the screen to the frame: the category includes a No. 200 replacement screen and an 8in No. 325 replacement screen. Confirm diameter and opening before ordering; screens and frames are separate components.
For drainage and water handling, match pans and tubing to the frame system. A wet test pan is listed for the 3in nonmetallic range; verify fit before combining ranges. Elutriation items such as the No. 170 elutriation sieve serve specific separation setups; confirm they match the intended method.
Verify Documentation and Follow the Method
Confirm the certificate or documentation supplied with the selected sieve, and any verification service separately. Wet-wash sieving requirements—water pressure, endpoint criteria, sample preparation—come from the test method, not from the category; never rewrite a procedure from general product copy.
For dry sieving and general particle sizing, compare the main sieving equipment selector, ASTM test sieves or ISO test sieves. Choose wet-wash equipment when the method specifically calls for washing fines.
