Magnetic Stirrer, Mixer Bar Spin Bar Teflon Octagon Magnetic Stirring Bar Bead 1.5 inch in Teflon

• Product Description:
  Achieve consistent, vortex-free mixing with this 1.5-inch octagonal Teflon magnetic stir bar. Designed for precision lab work, this stirrer bar is compatible with most magnetic stirrers and hot plates, ensuring reliable performance for chemical, biological, and pharmaceutical applications.

  Key Features:

  ✔ High-Quality PTFE (Teflon) Coating – Chemically inert, non-reactive, and resistant to acids/bases
  ✔ Octagonal Shape – Enhances mixing efficiency and prevents “jumping” during rotation
  ✔ Strong Magnet Core – Provides stable rotation even in viscous liquids (e.g., oils, glycerol)
  ✔ Autoclavable – Can be sterilized (up to 250°C) for repeated use
  ✔ Universal Compatibility – Works with 1.5L or smaller beakers/flasks
