Description
Sieve lid, 50 mm is a laboratory accessory for covering matching test sieves during particle-size analysis and sample preparation. With a defined diameter of 50 mm it sits securely on corresponding sieve frames, helping to retain material and limit external contamination while the stack is handled or agitated. The component is supplied as 1 pc and belongs to the laboratory-materials category used in quality-control, research and industrial testing environments. Produced by manufacturer NEXOPART, the lid originates from Germany (Nordrhein-Westfalen). Its straightforward geometry ensures straightforward integration into existing 50 mm sieve sets commonly found in analytical laboratories. The accessory supports routine workflows in which controlled particle separation, fraction collection or sample protection is required. Compatible with standard laboratory sieving practice, the 50 mm sieve lid provides a practical top cover that maintains stack integrity throughout preparation and measurement steps without altering the underlying sieve geometry or mesh characteristics.
This article is part of Test sieves (wire mesh), in Test sieves & mills.

Questions about Sieve cover, 50 mm
What is this article?
Sieve cover, 50 mm is the article on this page. Luminix Health distributes NEXOPART for laboratory use. It sits in Test sieves (wire mesh), inside Test sieves & mills, in Lab instruments.
A wire-mesh test sieve sorts particles through a woven opening of a stated nominal size. The frame diameter and the mesh are the specification. A sieve without a certificate is a screen, not a measurement.
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 Test sieves (wire mesh). The catalogue is Lab instruments.
Shelves beside this one are Test sieves (perforated plate), Mills, grinders & homogenisers, Sieve shakers and Sieve accessories (lids, pans, rings).
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.
