PULVERISETTE 23

Nº de encomenda

Acessórios

Please note: For the Mini-Mill you require 1 grinding bowl and the corresponding number of grinding balls. To avoid undesired contamination of the sample through abrasion, we offer a selection of 3 different material types. Normally, grinding bowls and balls of the same material are used. In principle, the grinding bowl material must be harder than the material to be ground.
Grinding bowls and grinding balls made of zirconium oxide for absolute metal-free grinding are also offered. Important: please keep in mind the specified useful capacity as this is not identical to the bowl volume.

  • Additional Information

    The specified ball filling per bowl is the minimum quantity and should possibly be increased depending on the material properties. The useful capacity depends on the type of material. In exceptional cases, the number of grinding balls can be reduced by up to 15 %. However, increased abrasion should be expected. In general, smaller grinding balls achieve finer grinding results.

    Normally, grinding bowls and balls of the same material are used. In principle, the grinding bowl materials must be harder than the material to be ground. Important: Pay attention to the specified useful capacity as this is not identical to the bowl volume!

    It may also be useful to work here with grinding balls ≤ 3 mm diameter. We have not listed these here because we would like to advise you regarding your application. Please contact Mr. Benes our laboratory supervisor. 

Various grinding bowls made of different materials for the Fritsch Mini-Mill Pulverisette 23

Please select 1 grinding bowl, which is offered in the sizes 30 ml, 15 ml, 10 ml and 5 ml or the container for single-use tubes to perfectly match your sample volume. The useful capacity of the grinding bowls can be found in the selection aid. For biotechnological use the PTFE bowl 5 ml and for smaller quantities the container for single-use tubes is especially suitable. For best grinding results the grinding bowls are available in different materials thus directly preventing contamination of the samples as a result of undesired abrasion.
