We tried using those as well as the Monsel's paste from Cardinal. The doctors complained that those weren't working for them, so I went back to the pints from Gallipot and repackaging them myself.
Gynex in Washington state sells Monsel's in Unit Dose. We have been using it for years at our hospital.
You can find them at www.gynex.com and it is item# 5055-W10.
They stopped selling Lugol's some time ago because of DEA restrictions - apparently some people were making Meth out of it.
