A sample probe wash chamber for cleaning the exterior of a sample probe. The probe wash chamber includes an interior threaded passageway between a wash fluid inlet and outlet. The inlet tangentially opens into an annular chamber formed adjacent one end of the threaded passageway. The outlet opens into a second annular chamber formed adjacent the other end of the threaded passageway and has a vacuum applied to it. The outlet can open perpendicularly into the second annular chamber to remove any moisture from the end of the sample probe positioned at the outlet opening. The probe wash chamber and the sample probe are movable with respect to one another and preferably the probe wash chamber is movable over the sample probe for multiple sample aspiration and cleaning operations.
