Less than 20mm length - Cylindrical Stir Bars

Buy <20mm Cylindrical Magnetic Stirrers and PTFE Teflon® Stir Bars

Choose from more than 20 small PTFE-coated BRAND® and Spinbar® magnetic stir bars. Select by size (2.5 to 20 mm), shape (cylindrical with pivot ring, or cylindrical/round), diameter (1.7 mm to 6 mm), and price. All stirrers in the table below are white and come in packages of 3 to 10.

Magnetic stirrers with pivot rings spin around a small raised area (ring) molded into the center of the bar. This pivot ring reduces contact with the vessel surface and is especially useful in vessels with an uneven bottom.

Spinbar® magnetic stir bars contain a permanent Alnico V magnet.

Our polytetrafluoroethylene (PTFE) products are only manufactured under a particular brand name where indicated.

We also offer several types of stir bar retrievers and a magnetic stirrer garage for safely storing multiple stirrer shapes and sizes. Appropriate storage also ensures that stir bars maintain their magnetization and effectiveness.
