Retsch recently introduced its newest mixer mill, the MM 301, which is particularly suited for dry and wet grinding of small quantities, as well as mixing and homogenizing powders and suspensions. A special feature of the MM 301 is its quick-action clamp on the grinding jar, which ensures easy handling during replacement of the grinding jars and optimizes reproducibility of the sample preparations. Higher sample throughput can be achieved due to the short duration of the grinding process and two grinding sites, and the enlarged swinging radius of the unit allows faster and finer grinding results. An assortment of new screw-top grinding jars is available in 25, 35 and 50 ml sizes. With the adapter racks, up to 20 safe-lock reactions can be processed at a time. The clamps will also accommodate deep-well plates.
