ASTM E161 Acrylic Frame Precision Electroformed Mesh Sieves offer greater accuracy for precision-particle sizing of small fine powder specimens. Electroformed Nickel Mesh openings are available from 150µm to 5µm, with tolerances to ±2µm. Precision Electroformed Sieves have a greater frame height, limiting the number that can be used in a stack.

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 frame sallows 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. Stacking height is approximately 1.4 (36.8mm) so fewer sieves can be used in a stack.
