Retsch releases a new pellet press to its product range. The PP 35 is a compact benchtop model which uses a maximum pressure force of 35 tons to produce smooth and stable pellets suitable for XRF analysis.
Before the sample can be pressed to a pellet, it needs to be ground to a homogeneous fineness below 100 microns. The MM 400 mixer mill is suited for homogenizing up to 8 x 30 ml sample material quickly and reproducibly. If the sample needs to be mixed with a binding agent for stability, there is a special adapter that will be clamped to the conical centrifuge tubes.
For the homogenization 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 100 microns within seconds. The pellet presses with 25 t and 40 t maximum pressure force to offer quick and reproducible XRF samples.
