Isolation of low copy plasmid

Hello all,
does anyone have experience to increase the yield of a miniprep from a low
copy plasmid (pET from Novagen, a pBR322 derivat) habouring E. coli
DH5alpha? Collecting multiple lysates on one spin column (Invotrogen`s SNAP)
yielded only poor quality DNA. Does Chloramphenicol-amplification works with
this vector?
