RETSCH has added the PP 35 new pellet press to its product range. The compact benchtop model uses a maximum pressure force of 35 tonnes to produce smooth and stable pellets suitable for XRF analysis.
Before a sample can be pressed to a pellet, it needs to be ground to a homogeneous fineness below 100 microns. RETSCH's MM 400 mixer mill is suitable for homogenising up to 8 x 30 ml of sample material quickly and reproducibly. If the sample needs to be mixed with a binding agent for stability, this can be done in conical centrifuge tubes which are clamped into a special adapter.
For the homogenisation of larger volumes of hard and brittle sample materials, Retsch offers two models of Vibratory Disc Mills, RS 200 and RS 300 XL. These achieve grind sizes below of 100 microns within seconds and are therefore highly
suitable for pulverising samples for pelletising. Pellet presses with 25 t and 40 t maximum pressure force complete Retsch’s offering for quick and reproducible preparation of XRF samples.
