Abstract
Method and apparatus for semi-automatic feeding of liquid samples from a plurality of sample sources to a scanning device are disclosed. The liquid samples are picked up from a preidentified sample source and delivered to the scanning device by use of a hand-held pick-up and delivery tube. The hand-held tube is releasably coupled to the scanning device for delivery of the liquid samples to the scanning device when coupled thereto. In the disconnected condition, particle free fluid flows in a reverse direction from the scanning device for automatic flushing of the scanning device and liquid sample supply line connected thereto. Visual display means for visually indicating to the operator which sample holder the next sample is to be obtained from is provided.
