A fully automatic system can perform most laboratory tasks without human interaction, while a modular approach automates only targeted functions. Modular devices are especially well-suited for automating front-end processes such as labelling, centrifugation, sorting, and aliquoting speciments.
One advantage of the modular strategy is that it spreads the costs of automating over a longer period of time and allows the laboratory to adopt a wait-and-see attitude with respect to the need for a larger system. The decision to use a modular, phased-in approach instead of purchasing a completely automated system depends on the size of the laboratory, throughput needs, and anticipated laboratory growth.
