I have searched and found people talking about that some of the cheaper Erlenmeyer flasks can have concave bottoms instead of flat and such, but I haven't been able to find if anyone has a solution.(By the way, mine was $30 from the LHBS for a 2L, so I wasn't really trying to go cheapo)
I am wanting to use this with my stirplate, but it keeps throwing the bar. I know it isn't an issue with my magnets not being lined up because I can put the stirbar into a flat bottomed bowl or even on a notebook on top of my stirplate and it spins like crazy with no signs of being thrown.
I am just wondering if anyone out there has come up with a solution for this at all? Otherwise I might try to take it back, although I bought it about 3 months ago, so likely they won't take it back even though there is no sign of usage.
