Wet-Wash Sieves

Wet washing material over a sieve using rinse water or a gentle spray serves as an effective sizing method when only one or two size fractions are being determined and fines can be discarded. Specimens that are fragile and non-soluble are optimal candidates for wet washing due to the gentler separating action of rinse water. Washing can also be used to prepare specimens with high fines content for effective dust-free handling and testing, or to isolate specific fractions for further testing. Gilson offers four different categories of Wet-Wash Sieves.

  • Deep Frame Wet-Wash Sieves are available with 3in, 8in, or 12in diameter brass or stainless steel frames in a wide selection of frame depths. All have permanently mounted stainless steel cloth. Deeper frames minimize water and sample loss during agitation and optional backing cloth can be specified for additional support.
  • Nickel Plated Wet-Wash Replaceable Mesh Sieves are available in 2in, 3in or 4in models and are corrosion-resistant with replaceable stainless steel mesh discs for drying in ovens or on hot plates.
  • Replaceable Mesh Wet-Wash Sieves are available with 4in or 6in deep, 8in diameter frames with screen assemblies that can be replaced quickly when worn beyond acceptable limits. Screen assemblies are stainless steel with built-in backing cloth.
  • Elutriation Sieves serve as an alternative to conventional wet-wash sieves for repeatable fines removal.
