Whitehouse Sieve Standards No.100 (150 micrometer)

Whitehouse Sieve Standards No.100 (150 micrometer)

Whitehouse Sieve Standards offer a reliable method for calibrating No. 6 (3.35mm) and finer sieves, ensuring traceability to NIST without the need to send sieves off-site. Calibrations take just minutes, allowing for quick, periodic checks to determine when sieves need replacement. Each Whitehouse Standard includes five single-use vials of precision glass beads designed for a specific sieve size. Use one vial for 8in or 200mm sieves and up to five vials for larger sieves, up to 18in or 450mm in diameter. The average aperture is easily determined using the included calibration graph.

Whitehouse has been selected by the Community Bureau of Reference (BCR) to produce standards for the European Community, with traceability to NIST, NPL, and BCR. These soda-lime glass beads, with a specific gravity of 2.45, are certified for size using electroformed sieves and validated through microscopy and image analysis.
