Disclosed is a device for processing biological material which at least comprises a chamber at least closable to the outside and having an inner space for receiving the biological material. The chamber comprises at least one electrode placed in contact with the inner space for generating an electric field. Also disclosed is a method for processing biological material. The biological material is introduced into the inner space above and the electrode can generate an electric field after said biological material is introduced by applying voltage to said electrode and a further electrode in contact with the inner space. The chamber comprises at least one inlet line having at least one opening arranged close to the electrode. The biological material is almost completely rinsed out of the inner space after the electric field is generated, via a solution guided via an inlet line of the chamber along at least one electrode.
