Beschreibung
PTFE sealing ring for grinding jar 12 ml is a precision replacement gasket intended for laboratory ball-mill systems. Fabricated from PTFE, the ring has a diameter of 37/26 mm and fits all classic-line grinding jars with a 12 ml volume. It restores a reliable seal that prevents sample loss or contamination during high-energy milling used in sample preparation for analytical chemistry and materials research. Supplied as a single piece with a net weight of 0,0010 kg, the component originates from manufacturer Fritsch and maintains full compatibility with the corresponding mill series. The chemically resistant PTFE construction withstands typical grinding stresses while remaining lightweight and easy to install. Laboratories performing routine particle-size reduction benefit from keeping this spare seal on hand to minimise downtime and ensure consistent milling performance across successive batches.
This article is part of Mills, grinders & homogenisers, in Test sieves & mills.

Questions about seal ring PTFE for grinding bowls 12 ml
What is this article?
seal ring PTFE for grinding bowls 12 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.
