Planetary micro mill for fine comminution
In various scientific fields, achieving extremely fine comminution for small sample sizes is essential. Whether dealing with geological samples, chemical substances, or biological materials, the challenge remains to uniformly reduce particle size to colloidal fineness efficiently and reproducibly.
Achieve fine comminution with centrifugal force
The Planetary Micro Mill PULVERISETTE 7 classic line by Fritsch is a high-performance tool ideally suited for quick and uniform comminution of very small samples. Utilizing the high-energy impact of grinding balls, the device achieves particle sizes below 1 μm with a maximum rotational speed of up to 800 rpm. The comminution process, which can be performed dry or in suspension, is highly efficient due to a centrifugal force of up to 50 g. The mill features two working stations, each capable of handling up to 20 ml samples, and is suitable for a wide range of applications including geology, mineralogy, ceramics, chemistry, and pharmaceuticals. A built-in fan enables cooling of the grinding chamber, allowing for extended grinding times, while the programmable microprocessor control ensures reproducibility. Various accessories are available to prevent sample contamination, making it a versatile solution for precise and controlled sample preparation.
