Description
Sealing ring, PVC 400 mm is a dedicated accessory for analytical test sieves employed in laboratory particle size analysis and materials testing. Constructed from polyvinyl chloride (PVC), the ring measures 400 mm in diameter and has a net weight of 0,03 kg, providing a lightweight yet effective sealing solution. It is designed to fit between sieve frames in a stack, creating a tight barrier that prevents sample escape and ensures reliable separation results during shaking or vibration. Offered as a single unit, this sealing ring from manufacturer NEXOPART is manufactured in Germany and finds application across quality control, research and industrial laboratories. The PVC material delivers the necessary flexibility and durability for both dry and wet sieving procedures commonly used with powders, granules and bulk solids. Its 400 mm size aligns with standard analytical sieve diameters, allowing straightforward incorporation into existing sieve sets. Consistent sealing performance supports accurate particle size determinations while maintaining sample integrity in pharmaceutical, chemical, food and materials laboratories.
This article belongs on Sieve accessories (lids, pans, rings), in Test sieves & mills.

Questions about Sealing ring, PVC 400 mm
What is this article?
Sealing ring, PVC 400 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.
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?
