Pellet Press

Solid, high-quality pellets are an important precondition for reliable and meaningful XRF analysis. With the Pellet Press, offers a pellet press which produces strong pellets with a smooth surface. The Pellet Press features individual pressure force regulation in the range of 0 to 40 t. It combines the advantage of a small benchtop unit with high press forces, which are built up automatically in three steps, ensuring that even difficult materials are pressed perfectly.

FUNCTIONAL PRINCIPLE

The steel ring or aluminium cup is inserted in the pressing tool of the Pellet Press 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.
