Looking For A Bell Jar Answered


I am a high school student from Boston, MA looking for a bell jar and corresponding stand/vacuum connection to conduct my experiments. I'm not looking for anything in particular, so long as it's not plastic (it will need to withstand some moderate electron bombardment).

If you have anything, even if it's only something you can only lend to me, I am interested!




do you think it would be possible to make one by cutting the base of a demijohn?

I bet it's possible, but I wouldn't trust any piece of large glass that I cut to withstand high vacuum.
