<p>A liquid handling apparatus is employed for washing the sidewalls of various laboratory vessels. The apparatus is particularly useful for washing the sidewalls of coated microtiter plate wells and for washing magnetic particles which are drawn to the sidewalls of a laboratory vessel having a side pull magnet. The apparatus includes a probe (5) having an inlet (6) and an outlet (7). The inlet aspirates liquid (2) from the laboratory vessel (1). The outlet (7) expresses liquid into the laboratory vessel (1). More particularly, the outlet is bent so as to direct the wash current against the sidewall (3) of the well (1) so as to create a swirling current of wash liquid (2) upon such sidewall (3). In the case of the magnetic particles, the bent outlet (7) serves to express wash liquid (2) with sufficient force so as to dislodge the magnetic particles (10), from the sidewall (3) of the laboratory vessel (1).</p> |
