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 and a wide selection of Wet Sieving Accessories.
