It sounds like you plan on drawing a vacuum on the flask in order to boil water that’s inside. If so, please don’t. There is a real danger that the flask might implode. We tape all our filter flasks against such a possibility. I would expect a 4-L flask to be even more “imperfect” and likely to break than the smaller ones we use. Get a Bell Jar.

Hi all,
I'm looking for a 4L filter flask for a demo but they all seem to be $150-$250. We are creating a vacuum in order to boil water. It needs to be that big because of the size of the lecture hall. Does anyone have a good website to turn to for glassware like this?
Thank you,
Sam
