Hello Morten!

I always reuse the Qiagen-Tips for a new batch of the SAME plasmid.
After elution equlibrate the column again with buffer QBT and seal 
the column with parafilm. Store it at 4 C. The yield of the following
purifications is about 80-90% of the first batch. I successfully 
reused the columns up to six times within half a year.
