An apparatus for washing pellets of magnetic particles magnetically bound to the bottom of a test tube employs a liquid handling probe having an aspiration channel with a forked inlet for positioning the probe onto the periapical region of the test tube for optimizing both the aspiration and expression of liquids. While contacting the periapical region of the test tube, the forked inlet may aspirate liquid adjacent to the pellet without contacting the magnetic particles. Furthermore, the contact between the forked inlet and the periapical region of the test tube, serves to position the outlet of the liquid channel directly over the pellet for dislodging and resuspending the magnetically bound pellet with a forceful stream of wash liquid.
