It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus, the sample is embrittled and volatile components are preserved.
The The CryoMill is a laboratory ball mill specifically designed for this application. It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus, the sample is embrittled and volatile components are preserved.
The liquid nitrogen is continually supplied from an autofill system in the exact amount required to keep the temperature at –196 °C. The CryoMill's versatility makes it the ideal grinder for sample quantities up to 20 ml.- powerful grinding by impact and friction with up to 30 Hz
- pulverization of two samples down to 5 micron
- The user never comes into direct contact with LN2 which ensures a high degree of operational safety
- adapter for keeping 2 ml plastic tubes or 2 ml steel tubes available
- special jar zirconium oxide available for heavy-metal free grinding
- suitable forgrinding in interval
- 3 different grinding modes (dry, wet or cryogenic)
- memory for 9 SOPs
- Screw-Top jars

... 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
