MM Series Video
 CryoMill Video
Specially designed for grinding, homogenising and mixing of small amounts of sample, in only a few seconds. Suitable for the disruption of biological cells as well as for DNA / RNA recovery.

MM 200 / 400:
  • 2 grinding stations.
  • Digital setting of grinding time and vibration intensity.
  • 9 parameter combinations can be stored.

Additional features MM 400:
  • Holder for grinding jars with automatic centring device and self-locking arrestor.
  • Equipped with screw-top grinding jars which make it suitable for wet and cryogenic grinding.

CryoMill:
Suited for cryogenic grinding of materials which cannot be milled at room temperature or where the structure would change. The grinding jar is cooled continuously with liquid nitrogen via an integrated cooling device, before and during grinding. Thereby the sample is embrittled and highly volatile components are maintained. Operates also without cooling.
  • Fast, efficient grinding and homogenisation at - 196 °C.
  • Especially safe due to automatic filling with liquid nitrogen.
  • Programmable cooling and grinding cycles.
  • Easy handling and cleaning.
  • 1 grinding station.
  • High final fineness thanks to oscillating frequency of up to 30 Hz.
  • Clearly structured user interface, memory for 9 parameter combinations.
