Abstract:

A system for cleaning a probe used in analytic equipment--for example, that used in analysis of body fluids--in order to reduce carry-over of materials from one sample to the next. A probe wash is provided in which the simultaneous introduction of pressurized air and water creates a turbulent flow including the use of a pressurized gas stream of short duration to blow the residue of the previous sample out of the probe prior to washing with additional diluent liquid. Also, a waste receptacle is provided which uses a filtered air vent and a liquid saturated material around the probe receiving opening to prevent the escape of aerosols from the receptacle.
