Globe Scientific’s Micro Stir Bars, also known as flea magnetic stir bars, are specially designed for precise stirring of small sample volumes in compact containers such as vials, test tubes, and gradient makers.

Ideal for life science and environmental testing applications, these lab micro stir bars ensure thorough mixing without disrupting sensitive samples.

Each stir bar is encapsulated in chemically inert PTFE (polytetrafluoroethylene) to protect both the internal strong alloy magnet and the surrounding sample. They are resistant to harsh chemicals, easy to clean, and suitable for repeated use in demanding laboratory environments.

Available in 7mm, 10mm, and 13mm lengths, these PTFE micro stir bars are sold in convenient packs of 2.
