Fisherbrand Magnetic Stir Bar Octagon 3 x 1/2 in. 8 Stirbars

The Fisher Scientific 1451368 Magnetic Stir Bar is a laboratory consumable designed for efficient and thorough mixing of liquids in various containers. This stir bar features an octagon shape, a common design that provides strong turbulence for effective stirring. It measures 3 inches in length and 1/2 inch in diameter, making it suitable for use in a wide range of flasks, beakers, and other laboratory vessels.

Magnetic stir bars are used in conjunction with magnetic stirrers, which create a rotating magnetic field that causes the stir bar to spin within the liquid. The octagon shape, combined with the specific dimensions, contributes to efficient agitation of the fluid, ensuring homogeneous mixing of solutions, suspensions, or reaction mixtures. These stir bars are typically coated with an inert material, such as PTFE (Teflon), to ensure chemical resistance and prevent contamination of the stirred liquid. The Fisher Scientific 1451368 Magnetic Stir Bar is an essential tool in chemistry, biology, and other scientific laboratories for a variety of mixing and reaction processes.
