3in (76mm) diameter Acrylic Frame Test Sieves are available fitted with either ASTM E11 woven-wire cloth or ASTM E161 Precision Electroformed Mesh. The clear frames offer enhanced visibility to monitor the separation performance of specimens during testing. These sieves are required for use with the GA-6 GilSonic AutoSiever Sonic Sifter.
- ASTM E11 Acrylic Frame Test Sieves are precision-machined to reduce sample loss. These sieves are supplied with ASTM E11 stainless steel woven-wire cloth in opening sizes from 5.60mm to 20µm (No. 3 ½ to No. 635). As well as their use with 3in sieve frame diameter capacity sonic sifters, they are also a recommended alternative to metal-frame sieves for the Gilson 3in Vibratory Sieve Shaker.
- 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.
