3in Acrylic Frame Sieves are required for the Gilsonic AutoSiever, and are a recommended alternative to metal-frame sieves for the Gilson Performer III Sieve Shaker, where the reduced height of the acrylic frames allow up to 14 sieves in a stack.
All meet ASTM E161 and ISO 565 requirements. Precision Electroformed Mesh Sieves feature tolerances to ±2µm, and when calibrated with Standard Reference Materials (SRMs), can be used as a reliable reference standard. The stacking height is approximately 1.4in (35.6mm), so fewer sieves can be used in a stack.
