Retsch PM300 Planetary Ball Mill
The Planetary Ball Mill PM 300 is a powerful and ergonomic benchtop model with two grinding stations for grinding jar volumes up to 500 ml. This setup allows for processing up to 2 x 220 ml sample material per batch. Thanks to the high maximum speed of 800 rpm, extremely high centrifugal forces result in very high pulverization energy and consequently in short processing times.
Applications: pulverizing, mixing, homogenizing, colloidal milling, mechanical alloying, mechanochemistry, co-crystal screening
Field of application: agriculture, biology, chemistry, construction materials, engineering, electronics, environment, recycling, geology, metallurgy, glass, ceramics, medicine, pharmaceuticals
