Reddit reviews Alcohol Burner - 4 oz

I've used the ones that are little butane tanks that you stick your existing burner to the top of, they tend to leak a little and aren't the greatest. Neighbors in the lab use camping stoves, which seem to work pretty well. I just use a cheap alcohol burner like this one and it serves my purposes fine.

They use a small alcohol lamp. Amazon sells them in appropriate sizes.

For example

Any replacement lamp will not automatically snuff itself, though. You will have to do this manually.
