module LabwareCreators
  # Handles the generation of plates where the source plate wells are normalised but are not rearranged
  # on the target plate (stamped).
  # The normalisation goal is to have a specific amount of DNA in the target wells (e.g. 50ng).
  # This amount to be in a specific target volume (e.g. 20ul).
  # There is also a minimum volume of source to take *e.g. 0.2ul).
  # The highest concentrated samples will have the minimum volume taken and be topped up with diluent.
  # The lowest concentrated samples will take the maximum volume with no diluent.
  # Once the normalisation is calculated the target wells are stamped onto the target plate without
  # binning or rearrangement.
