Description
Grinding ball 5 mm agate is a precision laboratory milling medium made from agate (SiO2) for use in ball mills. The 5 mm diameter spheres offer good abrasion resistance and are intended for soft to medium-hard sample materials. One hundred balls of this diameter weigh approximately 17 g, so the high ball counts needed for each grinding bowl can be set conveniently by weighing rather than individual counting. Recommended loadings scale with bowl size: about 2000 balls for a 500 ml bowl (useful sample volume 80–225 ml), 1200 for 250 ml, 250 for 80 ml, 180 for 45 ml, 80 for 20 ml and 50 for 12 ml, with further guidance for 15 ml, 10 ml and 5 ml bowls down to 20 balls. These grinding balls from manufacturer Fritsch support reproducible comminution of moderately hard materials while limiting media wear. Supplied as single pieces, they allow flexible replenishment of existing media sets across common laboratory bowl volumes from 5 ml to 500 ml.

Questions about grinding ball 5 mm agate
What is this article?
grinding ball 5 mm agate is the article on this page. Luminix Health distributes Fritsch for laboratory use. It sits in Mills, grinders & homogenisers, inside Test sieves & mills, in Instruments de laboratoire.
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.
Which category should I open next?
The category is Test sieves & mills. The sub-category is Mills, grinders & homogenisers. The catalogue is Instruments de laboratoire.
Shelves beside this one are Test sieves (wire mesh), Test sieves (perforated plate), Sieve shakers and Sieve accessories (lids, pans, rings).
What should I check before I order?
