Oval Stir Bars

Optimize mixing in curved vessels with our Oval Stir Bars, designed specifically for efficient stirring in round bottom flasks. Made from high-quality PTFE (polytetrafluoroethylene), these magnetic stir bars offer excellent chemical resistance, low friction, and long-lasting durability under routine lab conditions.

The oval shape enhances contact with curved surfaces, improving vortex formation and mixing efficiency where traditional cylindrical bars may fall short.

Key Features:

  • Constructed from PTFE for superior chemical resistance and low surface friction
  • Oval design ideal for round bottomed flasks and curved containers
  • Smooth, quiet operation with improved mixing dynamics
  • Compatible with most magnetic stirrers and laboratory mixing equipment
  • Perfect for chemistry labs, research facilities, and industrial applications

A go-to choice for labs that require magnetic stir bars tailored to the unique demands of curved-bottom vessels.
