Abstract
Apparatus and method for adding liquid to, aspirating liquid from, a rack of reaction tubes wherein a rack and carriage-dependent probes are made to move relative each other in the horizontal and vertical planes. The method calls for performing the first half of a wash sequence on tube located at x row, y column, then completing the sequence on tube at (x-1) row, y column, and returning to the tube at x row, (y+1) column to initiate the first half of the sequence. This 'backtracking' of probes permits an incubation-soak period without cumulatively extending the total rack processing time.
