Description
PTFE Stirring Bar is a Laboratory Device Featuring a Magnetic Core Encapsulated within a Chemically Inert PTFE Coating. When Used with a Magnetic Stirrer, It Couples with the Device’s Rotating Magnetic Field, Spinning to Create a Vortex That Ensures Efficient, Hands-Free Mixing of Liquids.
PTFE Stir Bar Shapes
| Shape | Features & Benefits |
| Octagonal | Most Commonly Used Shape with an Integral Pivot Ring |
| Interrupted Profile Provides Greater Surface Area and Added Turbulence | |
| The Multifaceted Surfaces Add Turbulence Relative to Smooth Cylindrical Bars | |
| Oval / Elliptical (Egg-shaped) | Particularly Well-Suited for Round-Bottom Flasks |
| Shape Mimics That of a Flask and Ensures Complete Mixing | |
| Maintains Stability Even at High Speeds | |
| Cross / Star-shaped | Provides Greater Mixing Action at the Bottom, Side, and Top of the Container |
| Creates a Deep Mixing Vortex with Stable Stirring at High Speeds | |
| Excellent for Dissolving Solids or Mixing Sediments | |
| Triangular / Wedge | Creates Turbulence Even at Slow Speeds |
| Acts as a Scraper, Good for Dissolution or Preventing Sedimentation | |
| Produces Significant Turbulence for Dissolving Salts |
