The FRITSCH Planetary Micro Mill PULVERISETTE 7 premium line features two grinding stations for efficient, high-energy comminution of hard, medium-hard, and brittle materials, achieving ultra-fine particle sizes down to 50 nm. The grinding bowls rotate oppositely to the main disk, causing grinding balls and samples to collide at high speeds with centrifugal accelerations up to 95g and rotational speeds up to 2,200 rpm. This delivers 150% more energy than conventional mills, reducing grinding times significantly. It supports dry, wet, or inert gas grinding, with various bowl materials like agate and zirconium oxide to prevent contamination. The mill includes SelfLOCK technology for secure, tool-free bowl handling, automatic safety checks, and a touchscreen interface with USB data export. Suitable for sample volumes up to 60 ml and feed sizes ≤5 mm, it’s ideal for precise, reproducible processing in laboratories and research across multiple industries.
