Beschrijving
Sieve insert square hole 4 mm P-15 stainless steel is a cutting-mill accessory that determines the final fineness of the processed sample. Square-hole sieve inserts are recommended for the comminution of brittle materials and materials of medium fineness that exhibit a narrow particle-size distribution. The 4 mm square perforation provides controlled size reduction and a defined upper particle limit during milling. Constructed from stainless steel, the insert is intended for general laboratory sample preparation in P-15 cutting mills where corrosion resistance and mechanical durability are required. It is supplied as a single piece from manufacturer Fritsch and has a net weight of 0,1500 kg. Sieve inserts of this type form an integral part of the milling system, allowing the operator to select the desired end fineness simply by exchanging the insert. The square-hole geometry is especially suited to brittle and medium-hard feed materials that benefit from a narrow particle-size band after grinding. Laboratories performing routine size reduction prior to further analytical steps can rely on this stainless-steel sieve insert for consistent performance and straightforward integration into existing P-15 cutting-mill workflows.

Questions about sieve insert P-15 stnl. steel 4 mm square perforation
What is this article?
sieve insert P-15 stnl. steel 4 mm square perforation 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 Instrumenten.
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.
Which category should I open next?
