FM1800 Seires freezer mill are cryogenic laboratory mills that cool samples to cryogenic temperatures, and pulverize them by ball shuttling back and forth against. Since the tube is closed, the integrity of its contents is maintained: hazardous or critical samples are easily controlled, cleanup is simplified, and cross sample contamination is eliminated. Because the liquid nitrogen surrounding the tube throughout the grinding cycle, the sample is kept at cryogenic temperatures and its key aspects preserved.
These composition or structure is altered by the heat generated by conventional grinding.
- The sample is always in the liquid nitrogen temperature during the grinding process
- 1 minute sample is cooled to -100 ℃, 4 minutes and 30 seconds to -196 ℃
- The tube is closed, the integrity of its contents is maintained
- The liquid nitrogen surrounding the tube throughout the grinding cycle, the sample is kept at cryogenic temperatures and its key aspects preserved.
