Variable speed rotor mill for sample preparation
Achieve rapid and precise grinding of various materials with a versatile mill that seamlessly integrates impact, shearing, and cutting processes, ensuring optimal sample preparation and enhanced cooling efficiency across demanding laboratory and industrial applications.
The FRITSCH PULVERISETTE 14 Premium Line is a versatile variable speed rotor mill designed for high-efficiency grinding operations across diverse industries including pharmaceuticals, plastics, and foodstuffs. It combines impact, shearing, and cutting comminution in one robust instrument, making it unique for applications ranging from polymer powders to biological samples. With a powerful rotative speed of up to 22,000 rpm, it ensures rapid sample throughput and fine grinding with a final fineness of d50 < 40 μm. The system integrates seamlessly into any production line, featuring an intelligent safety control system and options for both batchwise and continuous grinding. The milling chamber is available in stainless steel or other durable materials, ensuring resistance to chemical corrosion and easy cleaning with minimal downtime. Ideal for pilot-scale operations, it effectively reduces sample sizes while maintaining strong airflow cooling, perfect for temperature-sensitive materials. Compliance with safety standards assures reliable operation, while its modular design allows for customization to meet specific processing needs.
