I used to get jars from the chemist. I think they are only available if you are in the trade or something, so I got my chemist to order them in for me. Medical grade which is exactly what you need for something that can go rancid really quickly if air gets to it.
I suppose you could google medical supplies or something, but I'd think you would have to order in large amounts as a one off.
