Magnetic Stir Bars,10 Pcs PTFE Magnetic Stirrer Mixer Stir Bar, 20 mm/ 0.8 Inch White Laboratory Stirrer Mixer Bar (10)

absolutely perfect it works. Thank you so much. It’s very strong. It’s very light and a nice compact size. Very easy to use good for the money.

Perfect replacement mixer magnet. It snapped right onto the bottom of my cup and mixes my flavored water smoothly. I had accidentally tossed my original one, so having extras is going to be a lifesaver. Back to being boujee instead of shaking a bottle like it’s the Stone Age.

Work great on the magnetic stir plate. Spin well.

Strong magnetism, works on my homemade LEGO stir plate

Nice quality. Sometimes cheap stir bars can be unbalanced and wonky. These were not. These were top notch.

Not as happy with this brand as others, but they still work. They split at the seam and this makes them hard to clean. Will not reorder these—but they do work.

These things are complete garbage. I ordered mine back in December of 2025. They were in a few of my liquid cultures and didn't know how bad they were until I was finished with the cultures. Unfortunately a complete waste of money as I am obviously past the return window by months. They all cracked and/or rusted. Will NEVER buy these again and have thrown all the unused ones in the garbage. Lesson learned, thoroughly test your stir bars beforehand.

These were small. Although, these stir rods work okay for a half pint or 250 ml beaker.

El plástico no aguanta nada de calor, se rompieron al poco tiempo de uso. No recomendables
