Abstract
A chemical analyzer (10) includes a fluid dispensing system (46) with a carrier member (18) and fluid dispensing head (72). The carrier member (18) includes a docking fixture (52) and the fluid dispensing head includes a docking-receptacle (54). By engagement of the docking fixture and receptacle the carrier member carries the fluid dispensing head to a position above a recess (34) into which fluid is precisely dispensed. The carrier member also returns the fluid dispensing head to a storage location (64) substantially separating the fluids to be dispensed from the environment of the analyzer. When the fluid dispensing head is in its storage location the carrier member may disengage to perform other functions in the analyzer.
