Buffer Protection

From:Luis Chiriboga <luis.chiriboga@med.nyu.edu>

Hi all
I usually make large quantities of microwave solution on the order of
20L (I use a lot and I'm lazy). Has anyone ever added a preservative to
their buffer?  I occasionally get some growth (nothing bigger than an
occasional tadpole) in the carboy.  Azide is to dangerous, any other
recommendations? Has anyone ever had a problem with what they've added?
Thanks in advance
