16 - serial dilution hc (Copy)
https://protocols.opentrons.com/protocol/serial_dilution_hc (omitting final step, "dispense 200 uL to every even row") Note that we have duplicated the protocol twice: this makes it easy to arrange the wells as we want, with one column per node. Alternatively, we could have drawn the protocol once, but set "Number of duplicates" to 2 when taking the initial aliquot.
