About Bel-Art Spinbar Teflon Micro (Flea) Magnetic
The Bel-Art Scienceware round micro stir bar (also called a flea) and built-in pivot ring has a Teflon (PTFE) casing and an internal magnet made from alnico V (an alloy of aluminum, nickel, iron, and cobalt) for a range of laboratory stirring applications. The round, cylindrical shape provides better centering and creates less turbulence than a multisided shape. The bar's internal magnet is made from alnico V (an alloy of aluminum, nickel, iron, and cobalt). The magnet sits inside a Teflon (polytetrafluoroethylene, or PTFE) casing, which is chemically inert, can be used with corrosive chemicals, and helps reduce friction and wear while spinning. A built-in pivot ring on the stir bar minimizes contact between the bar and the container to help reduce vibration and wear during stirring. This micro stir bar is for stirring small volumes of liquid in containers such as test tubes, vials, and gradients. The bar measures 0.315 by 0.118" (L x OD, where L is length, the horizontal distance from left to right, and OD is the outside diameter, or circumference). The casing material is approved for use in food, drug, and cosmetic applications.Magnetic stir bars (sometimes called stirring bars, spin bars, or fleas) are used to stir a liquid or solution in biological, chemical, medical, and research laboratory applications. The stir bar is placed inside a container of liquid or solution that is seated on a magnetic stirrer (also called a magnetic mixer), which is a laboratory device that creates a rotating magnetic field using a rotating magnet or multiple stationary electromagnets. The rotating magnetic field causes the bar to spin, which stirs the liquid or solution. Stirring bars are offered in a variety of sizes and shapes, and they are encased in materials such as glass or plastic to help prevent contamination of the liquid or solution, to reduce friction, and to provide resistance to chemicals, abrasion, and heat. The bar may have a pivot ring or pivot point to minimize cont
