Description
Sieve cassette P-19 L chromium-free steel 6 mm square hole compatible with P-25 is a specialised sieve insert that sets the final fineness of samples processed in cutting mills. Fabricated from chromium-free steel ST12, it is particularly recommended for sample preparation according to RoHS and WEEE requirements, for example when detecting hexavalent chromium, and for XRF analysis. Square-hole perforations are advised for the comminution of brittle materials and materials of medium fineness that need a narrow particle-size band. While trapezoidal holes add shear action, the square geometry of this cassette delivers controlled size reduction. The P-19 L design is compatible with P-25 systems, enabling easy interchange of sieve cassettes. Supplied as a single unit with a net weight of 1,5000 kg from manufacturer Fritsch, the chromium-free construction avoids unwanted chromium contributions that could interfere with sensitive analytical methods. Laboratories focused on regulatory compliance testing or elemental analysis gain a durable, application-matched sieve cassette that maintains sample integrity throughout preparation.

Questions about sieve cassette P-19 L 6 mm square perf.
What is this article?
sieve cassette P-19 L 6 mm square perf. is the article on this page. Luminix Health distributes Fritsch for laboratory use. It sits in Test sieves (perforated plate), inside Test sieves & mills, in Lab instruments.
A perforated-plate sieve sorts particles through punched holes rather than a woven mesh. It is used for coarser cuts, where a wire would be too fragile. The hole size and the frame still have to be the stated ones.
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.
