Automated system for preparing a biological sample

An automated system for preparing a biological sample containing biological species, wherein the automated system comprises:

• a support plate wherein one or more through-wells are made,
• each through-well having two opposite accesses, a first access and a second access, the first access being separated from the second access by a filter-forming porous wall against which said biological sample that is to undergo lysis may be placed,
• and, for each well:
• a first mobile member, configured to be actuated to move translationally along an axis of the well so as to become inserted across the first access thereof,
• a second mobile member, configured to be actuated to move translationally along the axis of the well so as to become inserted across the second access thereof,
• a drive means driving the translational movement of each of the first mobile member and the second mobile member,
• a stimulation means of mechanical and/or thermal type for stimulating each first mobile member and/or each second mobile member and/or the support plate,
• a control unit, configured to:
• command said drive means, and
• command said stimulation means.
