557 5. Sample preparation Grinding/Mills GENERAL CATALOGUE EDITION 20 E & OE. Mixer Mill CryoMill The CryoMill is designed for the cryogenic size reduction of materials which cannot be ground at room temperature or whose composition would be changed by it. The grinding jar is cooled before and during the grinding process with liquid nitrogen through an integrated cooling system. Thus the sample is embrittled and its volatile components are preserved. The size reduction principle is the same as that of the well-proven Mixer Mill MM 400. The CryoMill can also be operated without the cooling system which makes it suitable for a wide range of applications. Features: - Powerful cryogenic grinding by impact and friction, up to 30 Hz - Closed LN 2 -system (autofill) for enhanced safety, avoids any contact of the user with LN2 - Screw-top grinding jars for convenient, leak-proof operation - Clearly structured user interface, memory for 9 SOPs - Wide range of accessories including LN 2 feeding systems, various jar and ball sizes, adapter racks, materials 1 Retsch Specifications Feed size up to 8 mm Ultimate fineness < 5 µm Charge max. 1 x 20 ml Adjustable frequency range 3 to 30Hz (180 to 1800 rpm.)
