Retsch . Rheinische Strasse 36. 42781 Haan, Germany. Tel +49 2129 5561-0, Fax +49 2129 8702. It is shown that the Retsch CryoMill polymers are ground to a significantly smaller fineness compared to other methods. Especially for inhomogeneous materials, small particles are the key for a high reproducibility.

The CryoMill is a cryogenic grinder designed with user safety in mind. The liquid nitrogen flows through the closed system and the user never comes into direct contact with LN2 which ensures a high degree of operational safety. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled.

With a vibrational frequency of 30 Hz the CryoMill grinds most materials very effectively in a few minutes. The combination of impact and friction leads to substantially finer grind sizes compared to other cryogenic mills. The CryoMill is equipped with one grinding station for grinding jar volumes of 25 ml, 35 ml and 50 ml.
