Mortar grinder Fritsch Pulverisette 2

Mechanical mortar for milling and mixing powders.

The mill is dedicated for milling and mixing of powders on the principle of friction using a pestle and bowl. The grinding bowl performs an eccentric rotary motion during grinding. The pressure of the pestle against the wall of the grinding bowl can be adjusted. The mill is equipped with a spatula, which ensures constant wiping of the material from the wall of the bowl. Grinding can be performed dry or in liquid. The mill can also be used for cryogenic grinding in liquid nitrogen. Grinding bowls made of corundum ceramics and WC-Co hard-metal are available for the mill.
