The instrument runs steadily and smoothly, even with heavy grinding sets, at maximum speed thanks to the new Stabilized-Plane-Drive.
With its robust design, the RS 200 has proven to be ideal for use in the building materials sector (cement), in geology, mineralogy, metallurgy and in power plants. Due to the high end fineness and speed the RS 200 is the perfect mill when it comes to preparing samples for spectral analysis.
Features - Reproducible results due to "Stabilized-Plane-Drive" (avoid tumbling of the grinding set)
- Safety interlock
- Variable speed 700 - 1,500 min-1
- Extremely short grinding time
- Agate recognition for automatic speed reduction
- 10 SOPs can be stored
- No sample loss thanks to optimum o-ring seal
- Wide range of materials for contamination free grinding
- Noise-insulated grinding chamber
- Quick-action grinding set clamping device

... Read More | The Planetary Ball Mill PM 300 is a powerful and ergonomic benchtop model with two grinding stations for grinding jar volumes up to 500 ml. This setup allows for processing up to 2 x 220 ml sample material per batch. Thanks to the high maximum speed of 800 rpm, extremely high centrifugal forces The Planetary Ball Mill PM 300 is a powerful and ergonomic benchtop model with two grinding stations for grinding jar volumes up to 500 ml. This setup allows for processing up to 2 x 220 ml sample material per batch. Thanks to the high maximum speed of 800 rpm, extremely high centrifugal forces result in very high pulverization energy and consequently in short processing times. The PM 300 is ideally suited for virtually all industries where the quality control process places the highest demands on purity, speed, fineness and reproducibility. Thanks to its enormous energy input of up to 64.4 times the acceleration of gravity, this mill is the perfect choice for tasks in research like mechanochemistry (mechanosynthesis, mechanical alloying and mechano-catalysis), or for ultrafine colloidal grinding on a nanometer scale.- powerful grinding by impact and friction with up to 800 rpm
- pulverization of two samples down to 100 nm
- jars from 12-500 ml
- adapter for keeping 2 ml gas chromatography glass vials for cocrystal screening
