In a method for extraction of a solid or semi-solid sample, an amount of a solvent (14) is caused to flow through an extraction sleeve (24) which is provided within an extraction unit (10) and contains the sample, said amount of solvent (14) is collected in one end of the extraction unit (10), and the collected amount of solvent is caused, by rotating the extraction unit (10), first to flow past the extraction sleeve (24) and then to flow again through the extraction sleeve (24) containing the sample. An extraction device for carrying the above method into effect comprises an extraction unit (10) with an extraction sleeve (24), a hollow extraction head (20), an extraction tube (12) and a connector (26). The extraction head (20) has an opening on which the extraction sleeve (24) is removably mountable. The extraction tube (12) has an open end (18) and contains the solvent (14). The extraction head (20) is partially insertable in the extraction tube (12) for fixing and/or closing the extraction tube. The connector (26) allows one-way transfer of the solvent (14) from the extraction tube (12) to the extraction head (20). |
