SP Bel-Art Spinbar Teflon Micro (Flea) Magnetic Stirring Bar; 3 x 3mm, White (F37119-0003)
- Round, cylindrical shape provides better centering and creates less turbulence than a multisided shape.
- Teflon (PTFE) casing is chemically inert, can be used with corrosive chemicals, and helps reduce friction and wear while spinning.
- 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.
- Internal magnet made from alnico V, an alloy of aluminum, nickel, iron, and cobalt.
- For stirring small volumes of liquid in containers such as test tubes, vials, and gradients.
