Solid, high-quality pellets are an important precondition for reliable and meaningful XRF analysis. With the PP 35, RETSCH offers a pellet press which produces strong pellets with a smooth surface.

The PP 35 features an individual pressure force regulation in the range of 0 to 35 t. The PP 35 combines the advantage of a small benchtop model with high press forces, which are built automatically in up to three steps, ensuring that even difficult materials are pressed perfectly.

作用原理

The steel ring or aluminium cup is inserted in the pressing tool of the PP 35 and filled with the sample material via a hopper. The complete slide is then pushed beneath the pressure plate and the pressing is started.

During pressure build-up the density of the powder increases. The maximum pressure force must be held over a certain period of time to allow full development of the interparticulate adhesive forces thus guaranteeing maximum stability. Pressing in up to three steps with e.g. increasing pressure force results in stable pellets.
