Pivot Ring Stir Bars

Engineered for consistent performance, our Pivot Ring Stir Bars are crafted from durable PTFE and designed to ensure efficient mixing across a wide range of laboratory applications. The central pivot ring allows for smooth, stable spinning—even on curved or uneven vessel bases—making them ideal for use in flasks, beakers, and other non-flat containers.

These PTFE magnetic stir bars resist most chemicals, offer low friction, and provide long-lasting performance for both routine and high-demand mixing tasks.

Key Features:

  • Central pivot ring ensures optimal spinning, even on uneven surfaces
  • Made from chemical-resistant PTFE for maximum durability
  • Low-friction surface enhances mixing efficiency
  • Ideal for use in flasks, beakers, and other curved-base vessels
  • Suitable for chemical labs, academic research, and industrial use

An essential part of any laboratory mixing toolkit, these pivot ring magnetic stir bars offer reliable performance and compatibility with most magnetic stirrers.
