ASTM Precision Electroformed Sieves

The ±2μm opening tolerances of Precision Electroformed Sieves comply with ASTM E161, ISO 565, and ISO 3310-3 requirements and are consistently more accurate than woven-wire sieves. Opening sizes are available to 5μm. The accuracy, efficiency, and size range of Electroformed Sieves make them a better solution for precision particle sizing operations. When calibrated with glass beads or other reference materials, electroformed sieves can serve as a reliable reference standard.

Electroformed sieve cloth is formed using electrodeposition of nickel, producing a planar mesh with very consistent square openings. Each sieve is measured at over 100 random openings and supplied with a Certificate of Compliance to meet listed standards.

Electroformed sieves have stainless steel 8in (203.2mm) or 3in (76.2mm) diameter full or half-height frames. 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.

Standard electroformed cloth has a support grid that increases strength and durability but blocks some openings and reduces sieving efficiency. To order sieves without this support grid, add a “U” to model numbers (price is the same), and contact Gilson Customer Service to order.

The cloth is bonded to the frame with an epoxy ring. Frames stack with woven-wire ASTM E11 test sieves.

Electroformed sieves are precision instruments, and ultrasonic cleaning is recommended for normal maintenance. Gilson assumes no responsibility for damage in use, and electroformed sieves are non-returnable when supplied as ordered.
