Description
Sealing ring for sieves 200 mm and 8'', NBR 3 mm is a replacement sealing ring made from NBR with a thickness of 3 mm. It is intended for analytical sieves of 200 mm diameter and 50 mm height, 8'' diameter and 2'' height, as well as 200 mm diameter sieves of 25 mm height. In laboratory particle-size analysis a reliable seal between sieve frames is essential to prevent sample loss and to maintain reproducible results during dry or wet sieving. The NBR elastomer supplies the elasticity and durability needed under the mechanical stress of sieve shakers and vibratory equipment. Supplied as 1 pc(s) with a net weight of 0,0090 kg, the ring installs quickly as a spare part on existing sieve stacks. This sealing ring from manufacturer Fritsch supports consistent performance in sample preparation, quality control and materials characterisation workflows. Laboratories performing granulometric determinations benefit from a dedicated sealing element that restores the interface between frames and helps preserve the accuracy of sieve analysis across a range of mesh sizes and sample types.
This article is part of Test sieves (wire mesh), in Test sieves & mills.

Questions about seal ring for sieves 200/50 mm NBR 3 mm
What is this article?
seal ring for sieves 200/50 mm NBR 3 mm is the article on this page. Luminix Health distributes Fritsch 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?
