The 6770 Freezer/Mill, from SPEX CertiPrep Ltd, is the next generation in our line of cryogenic mills, complete with state of the art electronics, including: touch screen interface, a removable control panel and on board self-diagnostics. These mills are used on samples normally considered difficult or impossible to grind at ambient temperatures: polymers, wood, bone, hair, rubber, plant and animal tissue, etc. The Freezer/Mill embrittles samples by immersing the grinding vial in liquid nitrogen, and then pulverizes them with a magnetically driven impactor. Low temperatures are retained throughout, preserving structural and compositional aspects degraded or volatilized during room temperature grinding.
The Freezer/Mill has unlimited applications, including preparation of samples for: DNA/RNA extraction from plant and animal tissue, recent or ancient skeletal material, trace-element analysis of hair, screening of asbestos containing materials, pharmaceutical research, diffraction studies of soft materials, food analysis, ceramics and glass and RoHS/WEEE applications, etc. Please contact our "grind" specialists to discuss your applications and to find out more about our free grinding and demo programs.
