What makes you think it's the PCR machine to blame? Are you observing rxn evaporation?

Not that I've got experience doing this rxn in 384's, but reducing the PCR
volume usually provokes inconsistent results due to a loss of stoichiometric
precision. So perhaps this is a set-up or post-processing issue?
