The Pellet Press PP 40 from Retsch is controlled with one single button and a graphic display which makes operation very easy and comfortable. The pressure force can be regulated in the range of 50 to 40 kN. Besides controlling the pressure force, it is also possible to determine build-up, maintenance and release of force during pressing. This reduces the inner tensions of the sample and ensures that even difficult materials are pressed perfectly. 32 parameter combinations can be stored. The press can be equipped with dies for different pellet sizes: Steel rings (inner diameter 35 mm or 32 mm), and aluminium cups (outer diameter 40 mm). The press provides stable pellets with a smooth and uniform surface which allows for reliable and meaningful analysis results.
