New in factory sealed package. Listing includes one Bel-Art Scienceware 377740131 PTFE Spinbar Magnetic Retriever, Yellow, 0.62" Diameter x 1.37" Length Removes magnetic stir bars from containers or non-magnetic drains and traps without requiring solution to be poured out of the container Flexible Teflon (PTFE) rod with built-in alnico V (an alloy of aluminum, nickel, iron, and cobalt) magnet at one end Comes in white, red, blue, or yellow color, for distinguishing retrievers among jobs Metal loop on one end for hanging storage Rod measures 13" (33 cm) long The Bel-Art Scienceware Spinbar Teflon (PTFE) magnetic retriever removes magnetic stir bars from containers or non-magnetic drains and traps in laboratory stirring applications. It does not require the solution or liquid to be poured out when retrieving the stir bar from a container. The retriever has a flexible Teflon (polytetrafluoroethylene, or PTFE) rod with a built-in alnico (an alloy of aluminum, nickel, iron, and cobalt) magnet at one end. The magnet is coated with Teflon and comes in a choice of white, red, blue, or yellow color, for differentiating retrievers among jobs. The rod has a metal loop on one end for hanging storage, and it measures 13" (33 cm) long. 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 contact with the container, reduce friction, and improve its spinning. The size and shape of the container and the volume and viscosity of the liquid or solution to be stirred determine which stir bar shape, size, and casing will suit a particular application.
