Product details:

Octahedral PTFE-coated magnetic stir bars with integral pivot ring are commonly used in laboratories for stirring small volumes in vessels such as vials, tubes and beakers. PTFE coating is inert to chemicals and increases the durability of the stirring bars. The octahedral shape (also called octagonal shape) has larger surface area and better turbulence when compared to the smooth surface of cylindrical bars. The pivot ring can reduce friction and chattering during the stirring.

What are Magnetic Stir Bars?

Magnetic stir bars are stirrers used with magnet forces to create a vortex for mixing a liquid or solution.

A number of factors affect magnetic stir bar efficiency and effectiveness, including its size, shape, and material. Sizes (L x Diameter) range from 6 x 3 mm to 100 x 10.5 mm.  Octahedral PTFE-coated magnetic stir bars are the most common magnetic stirrers used in the lab.  The multiple surfaces add turbulence to the mixing action. PTFE coating is inert to chemicals and increases the durability of the stirring bars.

MSE Supplies offers high quality magnetic stir bars for repeatable and reliable mixing results.
