Magnetic Stir Bars

Magnetic Stir Bar Info

Neodymium magnets (NdFeB) are super strong and are the strongest rare earth permanent magnets available. Our neodymium stir bar magnets have are a pill shape and have a specialized PTFE coating which is perfect for stir bar chemistry and many other applications. Stir bar magnets are used in research, science projects, brewing and stirring many types of liquids across various industries such as pharmaceuticals, biotech, food and beverage and more.

What is a PTFE coating? - PTFE stands for PolyTetraFluoroEthylene and is more commonly known as the trademark Teflon™. A PTFE coated stir bar magnet is the perfect solution for many stirring applications in chemistry as PTFE has many strong covalent bonds between carbon and fluorine, therefore making it less reactive than other materials.

How do I make my magnetic stir bar stronger? - You can make your stir bar magnet stronger by increasing the power of the magnet that is driving it or using a different configuration to increase the torque. See how to get more out of your stir bars in our Magnetic Stir Bars article.
