Description
Porcelain ball 42K size Ø 9 mm unglazed is a solid unglazed porcelain sphere with a diameter of 9 mm belonging to the 42K series. This laboratory material item is supplied as a 5 kg pack and provides uniform spherical porcelain elements for technical and research environments. The unglazed surface corresponds exactly to the stated finish, while the defined 9 mm diameter supports consistent handling in laboratory workflows that require porcelain balls of this size. Offered by manufacturer Haldenwanger, the product is categorised under laboratory materials and retains the simple geometric form of a porcelain ball without additional surface treatment. The 5 kg unit quantity facilitates bulk availability for repeated use or multiple setups. Dimensions remain fixed at Ø 9 mm, ensuring interchangeability within the 42K size designation. As a straightforward porcelain component, it integrates into existing lab inventories where unglazed porcelain balls of this diameter are specified. The combination of series coding, precise diameter and unglazed porcelain construction defines the essential characteristics of this item for laboratory material applications.

Questions about Porcelain ball, 42K, size Ø 9mm, unglazed
What is this article?
Porcelain ball, 42K, size Ø 9mm, unglazed is the article on this page. Luminix Health distributes Haldenwanger for laboratory use. It sits in Mills, grinders & homogenisers, inside Test sieves & mills, in Instruments de précision.
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.
