摘要

The invention concerns a device for grinding biological samples to extract DNA, RNA and proteins. The invention is characterised in that it comprises a plurality of rotary pestles supported on a pestle-holder block (1) and a lower mobile tray (5), mobile between a working position brought close to the pestle-holder block (1) and a quiescent position spaced away from the pestle-holder block (1), each of the pestles being provided with a catheter for dispensing liquid.
