Description
Sealing ring, PVC 200 mm is a specialised laboratory accessory intended for analytical sieve systems used in particle size determination and sample fractionation. Constructed from high-quality polyvinyl chloride (PVC), the ring provides an effective seal that maintains sample integrity during mechanical sieving processes. It features a diameter of 200 mm and a net weight of 0,02 kg, making it easy to handle and position within multi-sieve stacks. This component is particularly valuable in applications requiring precise separation of powders, granules, and particulate materials across various scientific disciplines. Laboratories in pharmaceuticals, food technology, environmental analysis, and materials research benefit from its reliable performance in both dry and wet sieving methods. The product comes as a single unit and is offered by manufacturer NEXOPART for compatibility with standard 200 mm test sieves. PVC material ensures flexibility combined with sufficient rigidity to withstand repeated use without deformation. By preventing cross-contamination and sample escape between sieve levels, the sealing ring enhances the accuracy of granulometric measurements and supports established laboratory protocols for sieve analysis. Its lightweight design facilitates quick assembly and disassembly of sieve columns in busy testing environments.

Questions about Sealing ring, PVC 200 mm
What is this article?
Sealing ring, PVC 200 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?
