    Abstract: A fluid transfer mechanism (10) for rapidly and accurately picking up or aspirating a fluid quantity or aliquot in one position, moving it to a second position and dispensing the aspirated aliquot. The mechanism can include an arm mounted at one of its ends on a high helix shaft (28) and driven up and down the shaft by a first motor (40) and rotated around the shaft by a second motor (38). The arm includes at its other end a fluid transfer probe (24) which is moved into and out of the fluids to aspirate and dispense the fluids in precise angular locations. The arm may be accelerated and deaccelerated as it is rotated to avoid vibrations and spilling of the fluid from the probe. The probe may include a level sensing structure for sensing when the probe has contacted a fluid surface. The probe can be coupled to an oscillator means (30) to oscillate the probe in a vessel into which the fluid has been dispensed to mix the fluids therein.
