Abstract
A liquid handling apparatus capable of being used as a fraction collector, sampler, dispenser, diluter or the like utilizes a microprocessor and three stepping motors to move a liquid handling tube suitable for dispensing, sampling or the like in two horizontal directions and in a vertical direction with respect to an array of test tubes or similar containers. The apparatus is capable of operating in several modes of dispensing and withdrawal operations, including modes based on the number of drops dispensed or the time spent over each container. The pattern of the movement of the liquid handling tube or dispensing head is selectable to suit the mode of operation of the liquid handling apparatus as well as the type of container and the number of containers being used at a particular time.
