Hi everybody, I have a 2800ml wide mouth conical flask I’m trying to find a stir bar to fit. Biggest on eBay looks like 100mm. It’s about a 7" diameter bottom. I found a few lab suppliers online that sell them for $200 each. Not trying to spend that much. Anybody know where to find these? I think 5-5.5" might be best.

Try s-a-le.nl he has some used ones in mint condition dirt cheap

6inch for $60. Are triangles good? I’ve only ever used the hex, and ovals
