Questions about Guide rod Classic / NEXOPART Twin Nut, 660 mm
What is this article?
Guide rod Classic / NEXOPART Twin Nut, 660 mm is the article on this page. Luminix Health distributes NEXOPART for laboratory use. It sits in Sieve accessories (lids, pans, rings), inside Test sieves & mills, in Lab instruments.
Sieve accessories are the lid, the pan and the intermediate rings that close a stack. The receiver pan is where the fines end. A lid from a different frame diameter does not seal the stack.
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?
The category is Test sieves & mills. The sub-category is Sieve accessories (lids, pans, rings). The catalogue is Lab instruments.
