... 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
- high energy input of up to 64.4 g
- suitable for mechanochemistry applications and mechanical alloying
- Ergonomic clamping unit with smooth surfaces
- Automatic grinding chamber ventilation with directed air stream for perfect jar cooling
- The Safety Slider prevents starting the machine without securely clamped jars, perfect stability on the lab bench thanks to FFCS -technology
- Comfortable parameter setting via Touch display
- 2 different grinding modes (dry, wet)
- memory for 12 SOPs and 4 program cycles
- 5 different jar materials
jars of 12 – 80 ml can be stacked (two jars each)
... Read More | The XRD-Mill McCrone was specially developed for the preparation of samples for subsequent X-ray diffraction (XRD). The mill is used for applications in geology, chemistry, mineralogy and materials science, quality control as well as R&D. Because of its unique grinding motion, the XRD-Mill McCrone The XRD-Mill McCrone was specially developed for the preparation of samples for subsequent X-ray diffraction (XRD). The mill is used for applications in geology, chemistry, mineralogy and materials science, quality control as well as R&D. Because of its unique grinding motion, the XRD-Mill McCrone is particularly effective for this analytical method: The 48 cylindrical grinding elements grind the samples gently via friction. The result is a short grinding time with almost no sample loss and an exceptionally narrow particle size distribution. The crystal lattice is almost entirely preserved during grinding operation, a pre-requisite for meaningful X-ray diffraction results.
Features: - Crystal lattice preserved during grinding operation
- Very narrow and reproducible particle size distribution
- Minimal cross contamination
- Compact, bench-top sized model
- Suitable for dry and wet grinding
