Description
Sealing ring Viton 250 ml SiN mounted is a precision replacement gasket manufactured from Viton elastomer and intended for use with the gassing lid of 250 ml silicon-nitride grinding bowls. The mounted design ensures accurate positioning and reliable sealing during milling operations that require controlled atmosphere or inert-gas purging. This spare part maintains the integrity of the grinding chamber, preventing leakage while withstanding the mechanical and chemical stresses typical of planetary ball-mill applications. Offered by manufacturer Fritsch, the sealing ring is supplied as a single piece with a net weight of only 0,0030 kg, making it a lightweight yet critical consumable for continuous laboratory milling workflows. It is specifically matched to silicon-nitride bowls of 250 ml volume and supports reproducible sample preparation in materials science, geology and advanced ceramics research. Dual-use classification is negative, confirming unrestricted laboratory use. The component contributes to extended equipment uptime by allowing rapid replacement of worn seals without compromising the original bowl geometry or lid fit.

Questions about seal ring Viton for grinding bowls 250 ml SiN
What is this article?
seal ring Viton for grinding bowls 250 ml SiN is the article on this page. Luminix Health distributes Fritsch 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.
