PTFE Magnetic Stir Bars for Magnetic Stirrer, Olive Shape, 10mm x 25mm - High Temperature Resistant, Stir Bar​ Set for Labs & Mixing (5 pcs)

Upgrade your mixing efficiency with our reliable PTFE magnetic stir bars. Designed to fit most standard magnetic stirrers, these olive-shaped stir bars​ deliver consistent performance for laboratory experiments, home brewing, DIY projects, and educational demonstrations. Key Features: Optimal Dimensions:​ Each stir bar​ is 10mm x 25mm (diameter x length), compatible with common beakers and flasks. The pack includes 5 pieces for added convenience. Premium PTFE Construction:​ Crafted from polytetrafluoroethylene, these magnetic stir bars​ are non-stick, chemically inert, and safe for use with aggressive solvents, acids, and bases. Enhanced Magnetic Design:​ Engineered with a strong embedded magnet to maintain secure coupling with your magnetic stirrer, enabling stable and vortex-free stirring. Wide Temperature Range:​ Performs reliably in high-temperature applications (up to 250°C) and low-temperature environments (as low as -196°C) without loss of functionality. Low Friction & Non-Adhesive Surface:​ PTFE’s naturally low coefficient of friction minimizes wear and prevents residue buildup, making cleaning quick and simple. Safe & Long-Lasting:​ Non-toxic and physiologically inert, these stir bars​ are suitable for sensitive applications. They also offer outstanding weather and aging resistance for prolonged use. Ideal For: Laboratory research and chemical mixing Home experiments, school science projects Stirring paints, inks, cosmetics, or culinary liquids Any scenario requiring consistent, hands-free mixing with a magnetic stirrer Package Includes: 5 x PTFE Magnetic Stir Bars (10mm x 25mm, olive shape) stored in a protective plastic bag. Note: Always verify compatibility with your magnetic stirrer​ device. For best results, avoid using with highly viscous materials beyond recommended limits.
