Based on our studies, we favor freeze crushing in a frozen ball mill apparatus, such as the Mikrodismembrator (S. B. Braun International). Freeze crushing involves shaking the frozen sample in a capped cryotube with a frozen steel ball. The containment in a cryotube during this phase reduces the risk of sample loss and the risk of contamination.
