Gilson 12in Sieve, All Stainless, Full Ht., #635 | Test Sieves

Conduct particle sizing procedures with confidence using the Gilson 12-Inch (305mm) All-Stainless-Steel ASTM Test Sieve (V12SF #635). Built to deliver reliable sieving results, this test sieve features a No. 635 (20µm) opening size that has been manufactured in compliance with ASTM E11 specifications. The frame and the cloth are crafted of stainless steel, helping ensure the longest possible service life, and allows the sieve to excel in applications that involve extreme wear, or harsh environments. Measuring 12 inches (305mm) in diameter, this testing sieve provides a generous surface area that accommodates more sample and less risk of overloading. Its full-height frame allows particles larger than a 1/2-inch to move freely during agitation, promoting more efficient separation of large particles. This Gilson test sieve meets the ASTM E11 and AASHTO M 92 requirements for Compliance-grade sieves. Each sieve includes an individual serial number and a certificate of manufacturing conformance. For applications that require a higher degree of accuracy and repeatability, Gilson also offers a Sieve Verification Service (available for purchase separately on Gilson’s website). The verification service measures the required number of sieve openings using an NIST traceable optical comparator after the mesh is mounted in the frame and certifies sieves meet Inspection- and Calibration-grade requirements, in accordance with ASTM E-11 specifications. Available in a wide range of mesh opening sizes, Gilson ASTM test sieves are suitable for testing soil, aggregates, concrete, asphalt, grains, spices, metal powders, paint pigments, pharmaceutical powders, and other applications where particle size is critical. Choose from a wide selection of Gilson sieving equipment to create a sieve analysis procedure that is accurate, reliable, and perfectly suited to your needs.
