3in Diameter ASTM Precision Electroformed Sieves
Electroformed sieve frames are stainless steel 8in (203.2mm) or 3in (76.2mm) diameter, full or half-height sieves. The Precision Electroformed cloth used in them is formed by electrodeposition of nickel compound to a base grid to form a mesh with very precise square openings.
All Precision Electroformed sieves meet the requirements of ASTM E161, with tolerances of ±2μm. Each sieve is measured and supplied with a Certificate of Compliance. While the initial price of Electroformed Sieves is substantially higher than woven wire sieves, their accuracy, efficiency and size range often make them a better solution for precision particle sizing operations.
Stacking heights for 8in diameter frames are 2in (50.8mm) and 1in (25.4mm). For 3in frames, stacking heights are 3in (76.2mm) and 1in (25.4mm). The Lines Per Inch (LPI) value in the Specifications Tab indicates the number of openings occurring in one linear inch (25.4mm). Higher LPIs are more fragile while low LPIs have thicker metal, but fewer openings.
3in (76mm) diameter ASTM Precision Electroformed Test Sieve has nickel woven-wire cloth with 70µm opening size and full height stainless steel frame.
Works well for very fine powders when used with Vibratory Sieve Shakers or Sonic Sifters.

The Gilson V3EF-070 is a 3in Precision Electroform Sieve designed for precision particle sizing operations. This sieve features a full height stainless steel frame with a 3in (76mm) diameter, making it ideal for use with very fine powders.
The Precision Electroformed cloth used in the sieve is created through the electrodeposition of a nickel compound onto a base grid, resulting in a mesh with incredibly precise square openings. This ensures greater accuracy of ±2µm, meeting the strict requirements of ASTM E161. Each sieve is measured and supplied with a Certificate of Compliance, guaranteeing its precision and quality.
Compared to woven wire sieves, Electroformed Sieves may have a higher initial price but offer superior accuracy, efficiency, and a wider size range. Therefore, they are often the preferred solution for precision particle sizing operations.
The Gilson V3EF-070 sieve has a 70µm opening size and is compatible with Vibratory Sieve Shakers or Sonic Sifters. It can efficiently and accurately separate particles of this size, making it an excellent tool for research, laboratory work, and quality control processes.
To meet different stacking requirements, this sieve is available in full or half-height options for both 8in and 3in diameter frames. The Lines Per Inch (LPI) value indicates the number of openings present in one linear inch (25.4mm). Higher LPIs indicate higher fragility and finer mesh, while lower LPIs offer thicker metal with fewer openings.
For added convenience and versatility, a range of accessories is available, including sieve pans, extended rim pans, sieve covers, and sieve covers with rings. These accessories ensure the efficient collection of fines passing through the sieve and prevent sample loss or contamination.
The Gilson V3EF-070 Precision Electroform Sieve complies with ISO 565, ASTM E161, and ISO 3310-3 standards, making it a reliable reference standard when calibrated with glass beads or other reference materials.
Overall, the Gilson V3EF-070 provides unparalleled accuracy and efficiency for precision particle sizing operations. Its superior performance, combined with its durable construction and compatibility with various accessories, make it a valuable tool for scientists, researchers, and professionals in need of precise particle separation and analysis.
