Bel-Art's Magnetic Stirring Bar Octagon Teflon is a PTFE (Teflon)-coated magnetic stir bar with an octagonal cross-section designed to produce a strong vortex and homogeneous mixing of solutions when used with a magnetic stirrer. Its Teflon coating is chemically inert, resistant to almost all solvents and reagents, and safe to use across a wide working temperature range in laboratories without contaminating samples.
This product is commonly used for stirring chemical solutions, preparing buffers and media, titration, and sample dissolution in analytical chemistry, biology, pharmaceutical, and quality testing laboratories. The octagonal design with a central pivot ring keeps it stable while spinning at the bottom of beakers, Erlenmeyer flasks, or round-bottom flasks, and it is available in various sizes to suit the volume of the vessel being stirred.
