Whitehouse Sieve Standards No.25 (710 micrometer)

Whitehouse Sieve Standards No.25 (710 micrometer)

Whitehouse Sieve Standards offer a precise and efficient method for calibrating No. 6 (3.35mm) and finer sieves, with full traceability to NIST. Calibration takes just minutes and eliminates the need to ship sieves back or take them out of service. Regular checks help determine when sieves need replacement. Each set includes five single-use vials of glass beads, designed for a specific sieve size. One vial is sufficient for 8in or 200mm sieves, while two to five vials can be used for sieves up to 18in or 450mm in diameter. After processing, the average aperture is easily determined using the included calibration graph.

Whitehouse has been chosen by the Community Bureau of Reference (BCR) to produce standards for the European Community. These standards are traceable to NIST, NPL, and BCR. The soda-lime glass beads, with a specific gravity of 2.45, are highly spherical and certified for size using electroformed sieves, further verified by microscopy and image analysis.

Whitehouse Sieve Standards for No. 25 (710µm) sieves include five vials, each containing 2.5g of glass beads.
