Description
Sieve lid, 350 mm is a laboratory cover intended for test sieves employed in particle characterisation and sample preparation. With a diameter of 350 mm and a net weight of 1,12 kg, it provides a matching closure for sieve frames of this size class. The lid is supplied as a single piece and sits securely on the top of a sieve column to keep material contained during mechanical sieving or interim storage. Produced by manufacturer NEXOPART and originating from Nordrhein-Westfalen in Germany, the accessory fits standard laboratory sieve systems without modification. It supports clean handling of powders and granules in analytical, research and industrial quality-control settings. Simple geometry facilitates cleaning and long-term use together with other sieve components. Laboratories that rely on standardised 350 mm sieves can incorporate the lid into existing stacks to maintain sample integrity between process steps. Stable seating and defined dimensions contribute to consistent laboratory practice in granulometric analysis and related material-testing workflows.
This article is part of Test sieves (wire mesh), in Test sieves & mills.

Questions about Sieve cover, 350 mm
What is this article?
Sieve cover, 350 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?
