The 6875D Freezer/Mill is a dual-chamber grinder that uses liquid nitrogen to freeze samples before pulverizing them, ideal for tough or heat-sensitive materials.
• Dual chamber grinder: load up to 100 grams of sample per chamber, two chambers are available for simultaneous use
• Liquid nitrogen auto-fill function enables simplified liquid nitrogen filling for convenient use and freezing of samples inside grinder
• Pulverize samples without blades or bits using a magnetically shuttling steel impactor to reduce cross-contamination and keep cleanup to a minimum
• Continuous liquid nitrogen immersion maintains cryogenic temperatures throughout the grinding cycle, preserving the structural integrity of thermolabile metabolites, isomers, and complex molecular species
• Touch-screen programmable controls for grinding cycles, time, impact rate, and pre-cooling/cooling times, for user convenience, up to 20 user-defined programs can be saved for frequently used protocols
