Description
Machine lid for dry sieving (Ø 400/300/305/315/350 mm) is a dedicated cover component engineered for dry-sieving machine set-ups that accommodate sieve diameters of 400 mm, 300 mm, 305 mm, 315 mm and 350 mm. With a net weight of 5,200 kg, this single-piece lid provides a secure closure over the sieving stack during dry fractionation and particle-size analysis procedures. It helps retain sample material, limit dust escape and support stable operating conditions throughout the sieving cycle. The lid is intended for laboratory and industrial quality-control environments that perform dry sieving on the listed diameter ranges. Manufactured by NEXOPART in Germany (North Rhine-Westphalia), the component is classified as laboratory material and carries no dual-use designation. Supplied as one unit, it integrates with compatible dry-sieving machines to complete the working assembly. Users benefit from a purpose-built lid that matches the stated diameter options, enabling consistent preparation and execution of dry-sieving workflows without the need for improvised covers. This accessory supports orderly, professional particle-analysis operations in research, production and testing laboratories.

Questions about Cover with inspection glass (Ø 400/300 mm)
What is this article?
Cover with inspection glass (Ø 400/300 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 Instruments de laboratoire.
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 Instruments de laboratoire.
Shelves beside this one are Test sieves (wire mesh), Test sieves (perforated plate), Mills, grinders & homogenisers and Sieve shakers.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
