... 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
