ABSTRACT:
An aspirator probe, such as is used with a disposable tip in a clinical analyzer. The probe is pivotable to allow for horizontal displacement error in seating the probe at a liquid-dispensing station. To reduce the amount of "tip flick" that occurs by pivoting the tip about the pivot point as the probe starts to withdraw from the liquid-dispensing station, the pivot point is located from the fulcrum at the liquid dispensing station, a distance that is at least five times the length of the disposable tip measured from the fulcrum.
