Laboratory mill for dry sample preparation
Achieve precise particle size reduction for pharmaceuticals and fine chemicals with high-speed grinding, ensuring consistent quality for your laboratory samples.

Reduces Particle Size for Laboratory Analysis
The POLYMIX PX-MFC 90 D from Kinematica AG is a versatile laboratory hammer mill designed for precise dry sample preparation across the pharmaceutical, chemical, and food industries. Featuring a robust construction with a gearless, maintenance-free motor, it combines hammer and cutting actions to efficiently process various materials, from brittle to fibrous, into fine powders. Ideal for producing tablet formulations and active pharmaceutical ingredients, it accommodates multiple industries by offering a range of grinding attachments and sieves, supporting particle sizes as fine as 40µm. Effortlessly integrating into R&D workflows, the mill ensures high precision with minimal manual intervention through its ergonomic dust-protected controls and illuminated display. With tools-free sieve changes and an automatic stop feature when accessing the grinding chamber, it prioritizes both user safety and ease of cleaning. The equipment meets stringent EMC and safety standards, providing reliable performance and engineered flexibility tailored to your specific sample preparation needs.
