Description
PTFE sealing ring 250/80 ml agate mounted is a replacement gasket produced from PTFE with a diameter of 85/70 mm for classic-line agate grinding bowls of 80 ml and 250 ml volume. The mounted design ensures a precise fit that maintains vessel integrity during high-energy milling and sample-preparation steps. In ball-mill applications where agate is selected for its hardness and low abrasion contribution, a reliable PTFE seal helps retain powders or suspensions inside the bowl and protects the surrounding equipment. The component is supplied by manufacturer Fritsch as a dedicated spare for the corresponding classic-line agate bowls and can be exchanged without altering bowl geometry. Packaged as a single piece with a net weight of 0,004 kg, it is convenient for stock-keeping and rapid maintenance. Laboratories engaged in materials research, mineral processing or analytical sample reduction benefit from restoring sealing performance promptly, thereby supporting reproducible grinding results and continuous operation of planetary or similar mill systems that utilise agate media.

Questions about seal ring PTFE for grinding bowl 250/80 ml agate
What is this article?
seal ring PTFE for grinding bowl 250/80 ml agate 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 Instruments de précision.
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.
