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.
The Gilson V3EH-045 is a 3-inch precision electroform sieve, half height, with an opening size of 45 micrometers. It is designed with electroformed sieve frames made of stainless steel, available in 8-inch or 3-inch diameter options. The precision electroformed cloth used in these sieves is created through electrodeposition of a nickel compound onto a base grid, resulting in a mesh with extremely precise square openings.
Meeting the requirements of ASTM E161 with tolerances of ±2 micrometers, each Precision Electroformed sieve is carefully measured and comes with a Certificate of Compliance. While the initial cost of electroformed sieves may be higher compared to woven wire sieves, their accuracy, efficiency, and wider size range make them the better solution for precision particle sizing operations.
The 3-inch diameter ASTM Precision Electroformed Test Sieve features a nickel woven-wire cloth with an opening size of 45 micrometers and a half-height stainless steel frame. It is highly effective for the sieving of very fine powders when used in conjunction with vibratory sieve shakers or sonic sifters.
The Gilson V3EH-045 sieve offers numerous features that set it apart. It provides greater accuracy with a tolerance of ±2 micrometers, making it ideal for precision particle sizing operations. Its compatibility with vibratory or sonic shakers makes it the perfect choice for very fine powders. Additionally, when calibrated with glass beads or other reference materials, the Gilson V3EH-045 serves as a reliable reference standard.
The package includes the 3-inch Precision Electroform Sieve with a half-height frame and 45-micrometer opening size, along with a Certificate of Compliance. For added convenience, optional accessories such as the V3SHXPN 3-inch all stainless sieve pan, half height, are available to collect fines passing through the bottom sieve. Other accessories like the V3SHXPE 3-inch all stainless extended rim pan, half height, the V3SFXCV 3-inch all stainless sieve cover, and the V3SFXCR 3-inch all stainless sieve cover with a ring help prevent sample loss or contamination.
The Gilson V3EH-045 meets international standards such as ISO 565, ASTM E161, and ISO 3310-3, ensuring reliability and accuracy in particle sizing. With a weight of only 1.0 pound (0.45 kilograms), this sieve is portable and easy to handle.
Overall, the Gilson V3EH-045 is a high-quality, precision electroform sieve that offers accuracy, efficiency, and compatibility with various particle sizing operations. It is the perfect choice for professionals who require precise and reliable results in their work.
