Single column microplate system and carrier for analysis of biological samples

A multiwall microplate for holding liquid samples, the multiwell microplate comprising:

• a frame defining
• a plurality of wells disposed in a single column, each well, having an opening with a length l1;
• a moat comprising a plurality of compartments and equalizer channels at each end of the multiwell microplate;
• and
• a plurality of walls traversing the moat, the walls defining the plurality of compartments of the moat, each compartment having a length l2 selected from a range of greater than l1 and less than 6l1,
• wherein the single column has at least two side walls, and at least two of the compartments are disposed on the at least two side walls of the single column of wells, and
• wherein at least two of the compartments are in fluidic communication via the equalizer channel and the equalizer channels connect compartments disposed on opposing side wails of the column.
