Product Description

hand, stir bar

Stir Bar Features

  • Made with PTFE material
  • Hydrophobic, high corrosion resistance, and very non reactive
  • Easy to clean
  • Octagon shaped with pivot ring or smooth with single ridge
  • Works with most magnetic stir plates

Stir Bar Tips

  • Proper speed is critical. Slowly increase your stir plate speed to find the stir bar's optimal performance. Turning the speed control up too fast can 'throw' the stir bar or might not spin it at all.
  • Depending on your stir plate's magnet strength and the container you use, it may take a few tries to find the perfect working position.
  • Check your stir plate specifications on optimal stir bar size. You may need to change sizes if you can't get the desired performance.
  • Stir bar magnets are delicate. Dropping one could degrade the magnet's strength or the resiliency of the soft PTFE plastic.

I mixed hot liquids. This is very reliable, has a good grip and a magnet. it’s long enough for a large beaker.

Works ok for the smaller stir bars. I wish the magnet was a little stronger to pick up some of the larger stir bars.

Junk can get caught on the lip of the magnet, where it connects to the rod. However, it's a very simple device and it works. I just wish the magnet had a smooth angle leading onto the rod, so it wouldn't catch stuff on the lip.

I use this for pulling the stir bar out of mixed drinks. It does what it's supposed to do.
