Magnetic Stirring Bar
Magnetic stirring bars are essential tools used with magnetic stirrers for uniform mixing of solutions in laboratories.
Each bar contains a strong magnet coated with PTFE (Teflon) for chemical resistance, ensuring compatibility with a wide range of reagents and solvents.
They are available in various shapes, sizes, and designs to suit different vessels and applications — including cylindrical, octagonal, oval, egg-shaped, triangular, dumbbell, and cross types.
The pivot ring on some models helps reduce friction and ensures smooth, consistent stirring action.
Features:
Chemically inert PTFE coating suitable for corrosive environments.
High magnetic strength for stable operation.
Available in multiple geometries to handle different liquid viscosities and flask types.
Reusable and easy to clean.
