A computer directed liquid handler which can take samples of specimen liquids out of two levels of a test tube, transfer the samples to assay wells and add reagents stored in other containers to the assay wells. The computer control circuitry allows the user to customize the liquid handling procedures and link more than one procedure to the other. Also disclosed is a wash block and method of washing wells and methods for sensing the liquid level in a test tube and for delivering multiple reagents to the same assay well without cross contamination. |
