Beschreibung
Sealing ring PTFE for grinding jar 45 ml is a replacement gasket intended for laboratory ball-mill grinding jars. Produced from PTFE, the ring has a diameter of 50/40 mm and fits all classic line grinding jars with a 45 ml volume. PTFE provides chemical resistance and dimensional stability under typical milling conditions, helping maintain a reliable seal during sample processing. The component weighs only 0,0010 kg net and is supplied as a single piece, making it a convenient spare for routine maintenance. It supports contamination-free operation by preventing leakage of powders or suspensions during high-energy grinding. Laboratories performing particle-size reduction, homogenisation or materials preparation rely on such seals to keep jars airtight and to protect both sample integrity and equipment. This accessory from manufacturer Fritsch integrates directly with existing classic line jars, allowing quick exchange of worn seals without altering jar geometry. Suitable for abrasive or chemically aggressive samples where durable sealing materials are required, the ring contributes to reproducible milling results and extended jar service life in research and quality-control environments.

Questions about seal ring PTFE for grinding bowls 45 ml
What is this article?
seal ring PTFE for grinding bowls 45 ml is the article on this page. Luminix Health distributes Fritsch for laboratory use. It sits in Mills, grinders & homogenisers, inside Test sieves & mills, in Präzisionsinstrumente.
A mill, grinder or homogeniser reduces particle size or breaks a tissue before an extraction. The rotor and the sieve insert decide the result. A knife mill and a bead mill are different machines. The sample has to tolerate the heat the motor puts into it.
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.
