For lab work, quality control, or material testing – this 12-inch diameter test sieve is built to ASTM E11 standards. It’s got a stainless steel woven-wire cloth with No. 200 openings (that’s 75µm), set in a solid intermediate-height brass frame. Overall height is 3 inches, stacked height is 2-1/8 inches, so it fits well in sieve stacks. Each sieve is individually serial numbered and comes with a certificate of conformance. You can also order it with a #35 stainless steel backing cloth for extra durability (that’s item V12CI #200 BU). Great for particle size analysis, aggregates, powders, soils, or any material sorting in industries like construction, pharmaceuticals, food, or research. The brass frame resists corrosion, and the mesh is precise and consistent. Reliable, compliant, and made for repeated use. Whether you’re in a professional lab or a school setting, this sieve delivers accurate, repeatable results. Sturdy, standard-compliant, and ready to work.
