Size:0.276" x 0.079" (7 x 2mm) The Bel-Art Scienceware round
micro stir bar (also called a flea) with square ends 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 with square
ends 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 ly inert, can be used with corrosive s, and
helps reduce friction and wear while spinning. The smooth surface
provides quicker cleanup and less risk of cross-contamination
than bars with pivot rings and allows the bar to spin on the
bottom of the container to disperse light sediment and air
bubbles. This micro stir bar is for stirring small volumes of
liquid in containers such as test tubes, vials, and gradients.
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, , 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 s,
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.Bel-Art Products manufactures scientific
