the throughput of automated system for a batch protocol by employing several instruments on different levels of stackers. Therefore, scalability is possible without increasing the footprint size of the automation system or changing the robotic arm of the system. Specifically, for the parallel and high throughput execution of a batch protocol, S1 (total footprint size of laboratory processing instruments in the system) is reduced to the value shown in (3) in a Tower-base automation configuration. This value is significantly lower than the value in traditional automation approaches indicated in (2).
