SP Bel-Art Spinbar Teflon Elliptical (Egg-Shaped) Magnetic Stirring Bar; 41.3 x 19mm, White (F37130-0158)

  • Egg shape (also called an elliptical shape) has a rounded pivot point to reduce friction, for use in round containers.
  • 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.
  • Internal magnet made from alnico V, an alloy of aluminum, nickel, iron, and cobalt.
  • Casing material is approved for use in food, drug, and cosmetic applications.
