Does anybody know where to pickup some bottles that are satisfactory for containing photochemistry? Not necessarily brand name scientific equipment, but a cheap alternative as I am on a budget. I am in Brisbane so something in QLD would be preferable but I know how it goes with supplies in Australia. I bought some glass bottles with stoppers at the local department store and they don't seem to be airtight. I don't need them to be amber as they are stored in total darkness.
