Two-piece nickel-plated Wet-Wash Sieves are corrosion resistant and use replaceable and interchangeable ASTM E11 stainless steel mesh discs with opening sizes from No.60 (250µm) to No.635 (20µm). Solder-free construction permits drying in ovens or on hot plates. Three threaded legs provide support and aid drying. Select sieves in diameters of 2in, 3in or 4in frame. Frames and Replacement Discs are ordered separately. Popular WT-62 2in Frame and WTA-49 #325 mesh disc are often paired for cement testing.
