Abstract
A chemical solution distribution system and method that includes or employs a plurality of liquid handlers where each of the liquid handlers includes a movable table that engages a sample multiwell plate and can align pipettes of the station with different subsets of wells of the multiwell plate where the number of wells of the multiwell plate is a multiple of the number of pipettes of the head of the pipette station. The system further includes and employs four different pumps to enable the system and method to supply four different solutions to wash stations of each of the four liquid handlers.
