8in Precision Electroform Sieve, Half Height, 25 um

8in 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.

8in (203mm) diameter ASTM Precision Electroformed Test Sieve has nickel woven-wire cloth with 25µm opening size and half height stainless steel frame.

Works well for very fine powders when used with Vibratory Sieve Shakers or Sonic Sifters.

The Gilson V8EH-025, 8in Precision Electroform Sieve, Half Height with a 25-micrometer opening size is an essential tool for precision particle sizing operations. This sieve features an 8in (203.2mm) diameter stainless steel frame, which is both durable and reliable.

The Precision Electroformed cloth used in this sieve is created through the electrodeposition of a nickel compound onto a base grid. This process forms a mesh with incredibly precise square openings, meeting the requirements of ASTM E161 with tolerances of ±2μm. To ensure quality and accuracy, each sieve is measured and supplied with a Certificate of Compliance.

Although the initial price of Electroformed Sieves may be higher than that of woven wire sieves, they offer unparalleled accuracy, efficiency, and size range. This makes them the ideal solution for applications requiring precise particle sizing.

The 8in diameter frames have stacking heights of 2in (50.8mm) and 1in (25.4mm), while the 3in (76.2mm) frames have stacking heights of 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, but offer finer openings, while lower LPIs have thicker metal but fewer openings.

This particular sieve has a 25µm opening size, making it suitable for very fine powders. When used with Vibratory Sieve Shakers or Sonic Sifters, it ensures accurate particle sizing and efficient separation.

The Gilson V8EH-025 Precision Electroform Sieve also comes with a range of accessories to enhance its functionality. These include an 8in All Stainless Sieve Pan, Half Height, for collecting fines passing through the bottom sieve, an 8in All Stainless Extended Rim Pan, Half Height, for collecting fines from the top sieves, an 8in All Stainless Sieve Cover to prevent sample loss or contamination, and an 8in All Stainless Sieve Cover with Ring, used in combination with 8in pans to prevent sample loss or contamination.

In addition to meeting the requirements of ASTM E161, this sieve also meets ISO 565 and ISO 3310-3 standards, ensuring its overall quality and reliability.

With its precise construction, reliable performance, and compatibility with various accessories, the Gilson V8EH-025 is a top choice for professionals needing accurate particle sizing for their operations.
