There are several sources.
You can often get them from the manufacturer of your miniprep kit
(the catalog # is written on the side of the bag they come in within
the kit). Many times, they don't list in their catalog that they
will sell it separately, but you can call and get them to give you a
price and such. This also goes for the individual bottles of reagent
that come in the kit (useful when somebody knocks a bottle over). I
have found that the bulk of the price of the miniprep kit is in the
spin columns, so you won't save much money getting spin columns from,
say, Qiagen.
For third party manufacturers we have used the tubes from UPrep
(http://www.uprepusers.com/) and they have worked fine.
I've also seen the tubes (from a different third party manufacturer)
advertised on eBay, but can't speak to their quality.
Best,

Hello,
Sorry for the off-topic question.....Does anyone know a way to just
buy the spin columns from the Qiagen (or similar) PCR clean up / Gel
extraction / miniprep kits, without buying the entire kit? Our lab is
deluged with buffer components but seem to be perpetually running out
of the columns.
Thanks
Eric
