Description
Sieve insert trapezoidal hole 1 mm P-15 stainless steel Conidur fine perforated sheet determines the final fineness of the sample during laboratory milling. Trapezoidal holes generate additional size reduction through increased shear action, making the insert suitable for materials that benefit from enhanced shearing. Constructed from stainless steel as a Conidur fine perforated sheet, it offers the hardness and abrasion resistance preferred for general applications. This component from manufacturer Fritsch is supplied as one piece with a net weight of 0,099 kg and fits P-15 cutting mills directly. Square-hole inserts are recommended for brittle materials of medium fineness with a narrow particle-size band, whereas the trapezoidal design excels where extra shear is desired. For RoHS- and WEEE-compliant preparation or XRF analysis requiring chromium-free contact surfaces, dedicated ST12 inserts are advised; the present stainless-steel version serves routine laboratory workflows that prioritise durability and consistent end-fineness control.

What is this article?
sieve insert P-15 stnl. steel 1 mm trapezoidal 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.
