ORBMicroball Mill


The ORBMicro Ball Mill is a laboratory machine, which is suitable for milling and homogenizing soft, fibrous, hard and brittle materials in the dry and wet state. It is used for fast, super fine milling of 2 samples simultaneously from 0.2 ml up to 160 ml.

The closed milling system guarantees complete recovery of the samples. Owing to the extremely short milling time and the high final fineness of the milled material, the ORBMicro Ball Mill is also ideally suitable for sample preparation for all spectral analyses.

Final finenesses of down to 1 μm can be achieved, depending on the milling time and the specific properties of the sample material. The optimum milling cup filling is as a rule 1/3 of the milling cup volume. Exceptions to this are voluminous materials, such as wool, leaves, grasses and suchlike. In these cases a filling level of 70-80% is necessary.
