Cylindrical Stir Bars

Achieve consistent, efficient mixing with Globe Scientific’s Cylindrical Stir Bars, designed for superior performance on magnetic stirrers and hotplate stirrers.
Constructed with strong alloy magnets fully encapsulated in pure white PTFE (polytetrafluoroethylene), these lab stir bars offer outstanding chemical resistance and durability under demanding lab conditions.

Supplied in polarity-aligned packs, these magnetic stirring bars ensure maximum magnetic coupling strength for smooth, uninterrupted stirring—even at higher speeds.

Built to withstand virtually all chemical attacks and temperatures up to 260°C, these PTFE magnetic stir bars are the ideal choice for chemical laboratories, research facilities, and industrial environments.

Key Features:

  • Manufactured from strong alloy magnets sheathed in pure white, inert PTFE
  • Cylindrical design ideal for uniform stirring of liquids
  • Compatible with magnetic stirrers and hotplate stirrers
  • Supplied in polarity-aligned packs for maximum coupling efficiency
  • Resistant to most chemicals and stable at temperatures up to 260°C
  • Perfect for chemical labs, pharmaceutical research, and general laboratory mixing

Applications:
These chemical-resistant cylindrical stir bars are essential tools for a wide range of laboratory mixing tasks, from routine sample preparation to critical research requiring reliable, contamination-free stirring.
