Retsch, Haan, Germany, claims that no grinder can beat the speed of a vibratory disc mill when it comes to preparing samples, for example for XRF analyses. In addition to its well proven RS 200 vibratory disc mill, the company is now offering the RS 300 XL for sample volumes up to 2000ml. This new model allows for simultaneous processing of up to four samples. Thanks to the robust universal drive shaft, which sets the grinding jar into a 3-D motion, it accepts grinding sets weighing up to 30kg. The RS 300 XL very effectively grinds hard, brittle and fibrous samples like cement, coal, minerals or electronic components by impact and friction. Grind sizes below 50 microns are typically obtained in a matter of seconds. For safe operation the grinding set is firmly attached to the vibration plate with a pneumatic clamping device. A selection of grinding jar materials and sizes makes this mill versatile and suitable for grinding a variety of sample materials without affecting analysis results. www.retsch.com
