Description
Test sieve 8/2'' MW = # 40 ASTM (0,425 mm) is a stainless-steel analytical sieve with an 8'' diameter and 2'' height frame. The rim and woven mesh are both fabricated from stainless steel, providing a durable mesh opening of 0,425 mm that corresponds to ASTM mesh number 40. This single-piece laboratory sieve is designed for particle-size determination, fractionation and quality-control screening of powders, granules and bulk solids. Manufactured by Fritsch, the sieve is also available in alternative frame sizes such as 200 mm diameter with 50 mm or 25 mm height and 100 mm diameter with 40 mm height, allowing adaptation to different sample volumes and sieve-stack configurations. The robust stainless-steel construction withstands repeated wet or dry sieving cycles while maintaining dimensional stability of the 0,425 mm aperture. Supplied as 1 pc with a net weight of 0,50 kg, the unit integrates readily into standard sieve shakers and manual screening workflows used in materials testing, pharmaceuticals, food technology and mineral processing laboratories.
This article is part of Test sieves (wire mesh), in Test sieves & mills.

Questions about test sieve 8/2'' mesh = 40 ASTM (0.425 mm)
What is this article?
test sieve 8/2'' mesh = 40 ASTM (0.425 mm) is the article on this page. Luminix Health distributes Fritsch for laboratory use. It sits in Test sieves (wire mesh), inside Test sieves & mills, in Instruments de laboratoire.
A wire-mesh test sieve sorts particles through a woven opening of a stated nominal size. The frame diameter and the mesh are the specification. A sieve without a certificate is a screen, not a measurement.
A test sieve sorts particles by whether they pass an opening. Wire mesh and perforated plate are two ways of making that opening, and the nominal size is not a suggestion. A sieve shaker repeats the motion so the result does not depend on how hard someone shook by hand. A mill or grinder makes the particles smaller before they are sieved. The certificate of the sieve, and the opening size, are what an audit asks for. Measurement practice around mass and dimension sits with the BIPM, EURAMET and BELAC.
Which category should I open next?
