Default Pivot ring stir bar

My buddy and I are making our first stir plate but the only stir bars we have been able to find typically have something called a pivot ring on them. Is this a big deal or should we keep looking to find one without the ring?

One of these stirbars and 2 magnets (links below) make for an incredible noise-free setup that will stir anything (expecially glass gallon jugs with curved bottom). I've tried other computer hard drive magnets and there's no comparison to a pair of these.

The pivot ring in the middle is a GOOD thing. It helps the ends of the stir bar stay off the bottom and helps it run more quietly. I don't have the pivot ring on my stirbars, but I have added a silicone o-ring to the middle of each one.

yep, o-ring works nicely - a Keg diptube o-ring is a nice fit.

I bought a stir plate and lost the original magnet that came with it. I bought a six pack of magnets (same size as the original) but the new magnets were octagonal and they had a pivot ring on them. They didn't work well at all. Turning the stir plate to anything higher than about 25% speed threw the bar.

Solution: I took a razor blade and sliced off the pivot ring. Worked like a charm.

Yes the o-ring works great! You shouldn't have any issues.

FYI, the dip tube o-rings will be rubber so don't boil them with the stirbar. If you decide you want to boil you can use some of these instead:
