Zusammenfassung:Apparatus for distributing a solid, gel, powder, granular liquid or viscous liquid test substance in an extraction fluid comprises a flow cell 2 for holding the test substance 16 wherein the cell comprises a extraction chamber 8, a grinding surface 10, an extraction fluid inlet 4 and an extraction fluid outlet 6, a grinding head 9 disposed within the extraction chamber and a re-circulating pump 14 for driving extraction fluid into the flow cell via the extraction fluid inlet through the extraction chamber and back to the flow cell via the extraction outlet. The grinding head is mounted on a rotatable, reciprocating spindle such that the grinding head, whilst rotating, moves towards the grinding surface so that a test substance such as a drug capsule, pill or tablet is crushed, ground and pulverized. The grinding surface comprises a plurality of teeth 11. The grinding head is loose fitted within the extraction chamber so that fluid can flow around the grinding head.
