Magnetic stirring bars provide effective stirring of samples via magnetic manipulation. Many models feature an octagonal shape with a central integrated pivot ring for optimal turbulence while stirring thanks to a greater surface area. The heavy-duty magnetic strips is one of the frequently used tools, strong enough to hold the solution. Commonly coated in Teflon to provide chemical inertness, occasionally glass will be the coating for use with most liquid alkali metals and alkali metal solutions in ammonia. Both of these coatings are inert and will not contaminate or react with the reaction solution.

Magnetic stirring bars, oval
Supplier: COWIE
PTFE covered. For stirrers with rare earth magnetic core the magnetic attraction is 1,5 to 2 times stronger than conventional stirrers. The magnetic core is made from a combination of samarium and cobalt. The rare earth stirrers will continue to function at full strength for many years as the magnetism remains for longer.
