7pcs/Pack Mixed Size PTFE Magnetic Stirrer Mixer Stir Bars Type-B Set

The 35mm, the two 30mm, and the 15mm worked great! The 25mm, the 20mm, and the 10mm didn't work well, as they seemed unbalanced, so they were noisy and it was very hard to get them to work. I am using these with the INTLLAB Magnetic Stirrer.

Great

I bought these to replace my LOST set... And the LOST ones turned up right AFTER two uses of the new ones. These work very well for me and have a nice little case. SO... I hope not to lose any of these.

These are PTFE coated magnetic stir bars. They do the job quite well. I'd highly recommend them if you're doing anything where you need these. Decent price, and definitely good quality. Mine had a NICE thick coating, such that one of them fell in the garbage disposal, and made a terrible noise when I turned the thing on. After extraction, I saw a pretty heavy cut in the coating, but it wasn't cut all the way through. I use mine for food, so that one's in the trash (better safe than sorry) but if you're doing something else, this would probably have still worked fine after being in the garbage disposal (that noisy thing in your sink that beats up food and allows it to go down the drain, if you're reading this from some location where you don't use that same term.).Would buy again.

Thanks

The media could not be loaded. Nice selection of sizes spill well on the plate with thick oil

Got the set of stir bars to replace one that i lost that came with my stir plate. The stir bars seem to work fine testing them with a 2L Erlenmeyer flask. No issues, would recommend to others looking for cheap, functional stir bar set. Using them for yeast starters, so nothing complicated. Good deal!

These magnetic stirrers worked very well. I would recommend them.
