Micro Stirring Bar can be used for stirring test tubes, micro-beakers, and other small containers. The stir bar is covered in blue / red / yellow PTFE resin and features an Alnico V magnetic core which is one of the most powerful permanent magnet alloys available. Stir bar should not be stored in a random mass or dropped on a hard surface, especially steel. Stir bar should be stored in pairs to maintain magnetic strength. Color may leach in harsh chemicals.

Micro Stirring Bars are available in white and various other colors for easy sample identification throughout your laboratory benchtops. Dynalon stir bars feature ALNICO V magnetic cores which are one of the most powerful permanent magnet alloys available. Stir bars should not be stored in a random mass or dropped on a hard surface, especially steel. Stir bars should be stored in pairs to maintain magnetic strength. In general, PTFE thickness accounts for 18% of stir bar diameter. Note: Colored magnetic stir bars may leach out in to sample when used with extremely aggressive chemicals. If you are stirring more aggressive chemical samples, be sure to use white PTFE stir bars rather than the colored PTFE magnetic stir bars.

These color-coded Micro Stirring Bar come encapsulated in FDA approved PTFE with Alnico V magnet cores. They are nicely polished to reduce pick-up and cross contamination and can be sterilized using thermal or chemical means. To prevent demagnetization please do not store bundles of random stir bars together, do not drop on hard (especially steel) surfaces, and try to store in identical pairs. A couple of recommendations for choosing stir bars….stirring is most effective when the distance between the poles in the drive magnet (in the stirrer) is most similar to the length of the stir bar. Also, the closer the proximity of the drive magnet (in the stirrer) to the stir bar, the more advantageous. The pictured stir bar is exactly what you recieve.
