With Retsch mechanical laboratory mortars, you can adjust the pestle pressure and digitally set the time to ensure reproducible grinding, grinding and mixing results. The wide selection of grinding head materials for mechanical laboratory mortars allows for fast and contamination-free grinding.

Retsch GmbH also offers three scraper materials to choose from, depending on the desired grinding tasks. The operation of Retsch mechanical mortars is easy and intuitive for the user, as the pestle and mortar change does not require any additional tools and the external display shows the load of the motor in operation.

Grinding in a mechanical mortar is performed by pressure and friction. The substance is forced into the field between the mortar and pestle by a scraper. The forced feed guarantees continuous and intense grinding and abrasion of the sample. The required grinding and abrasion pressure is achieved by adjusting the weight of the pestle and the spring pressure acting on the pestle axis.
