| 摘要 |
The invention relates to an improved system for cleaning of a probe (10) used in analytic equipment, for example, that used in analysis of body fluids, between samples 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 (35) is provided which uses a filtered air vent (38) and a liquid saturated material (42) around the probe receiving opening to prevent the escape of aerosols from the receptacle. |
