Pulverizer and corresponding method for preparing a biological sample for processing

A method for disrupting a biological sample, wherein a solid biological sample having a temperature of below −50° C. is introduced into a sealable container cooled below −50° C., in which a moveable body cooled below −50° C. is located that is set in motion after the container has been sealed and crushes the biological sample, wherein the container is neither cooled during crushing, nor are cooling media nor chemical substances introduced into the container during or prior to the disruption which are still present in the container during the disruption.

A method for preparing the processing of a plant or animal sample, wherein the sample is first washed and then stabilized, wherein the sample, subsequent to stabilization, is deep-frozen, wherein a sealable container with a moveable body located therein is deep-frozen, wherein the deep-frozen sample is introduced into the deep-frozen container with the moveable body located therein, the deep-frozen container is subsequently sealed and the deep-frozen container is shaken back and forth and a sample crushed thereby is subsequently removed.
