Hi, I don't think your method is good because it might introduce possible contamination to your DNA sample. If the diluted DNA concentration was not the one you need to do your experiment, it is advisable that you re-extract the DNA.

Rob Darrington

Evaporation will remove the solvent (water) but you will concentrate the buffer salts. This may be a problem.
