Apparatus and a method for mixing a liquid within a disposable aspirating probe tip so that most of the liquid is forced to move past a transition zone between two different inside diameters to cause rotational mixing. The apparatus and method can be used to provide agglutination of blood, which in turn can be used for blood typing. The probe tip can include a single integral piece, or two separate portions. The transition zone can include a sharp demarcation between inside diameters, or a smooth one.

A method and apparatus for detecting improper liquid content of a metering tip of an analyzer. The method detects the content or status using radiation between 630 and 2000 nm, and comprises the steps of: a) aspirating the liquid into the tips; b) scanning the liquid; c) providing relative motion between the tip and the scanner while simultaneously scanning the liquid; d) detecting the amount of light transmitted to detector at all levels of the liquid; e) comparing the detected light with light known to be transmitted at levels of liquid free of air bubbles; and flagging the results.
