Magnetic Stirring Cylindral Stir Bar Rod PTFE Teflon Coated (Cylindrical, 5"(125mm)*1)

LUERFLEX Magnetic Stirring Cylindral Stir Bar Rod PTFE Teflon Coated

• 1. High-Performance Neodymium Core for Maximum torque Equipped with a powerful neodymium (NdFeB) magnet core, this stir bar delivers exceptional magnetic strength and rotational stability. It maintains reliable coupling with stir plates even at high speeds or in thick, viscous fluids.
• 2. 100% Pure PTFE Coating for Full Chemical Inertness Encapsulated in seamless, lab-grade PTFE, the stir bar is resistant to virtually all acids, alkalis, and solvents. It guarantees zero contamination of sensitive solutions and is ideal for applications requiring ultra-pure mixing.
• 3. Autoclavable & Temperature Resistant Suitable for sterilization by autoclaving (up to 121°C/250°F). The PTFE shell and neodymium core are engineered to withstand repeated thermal cycling, making it perfect for sterile cell cultures and critical reactions.
• 4. Smooth Rotation & Low-Profile Design Precision-balanced for wobble-free stirring and silent operation. Its streamlined shape minimizes turbulence and ensures consistent mixing in beakers, flasks, and bottles without interrupting workflows.
• 5. Versatile Use Across Lab & Industrial Settings An essential tool for chemistry labs, pharmaceutical preparation, educational demonstrations, and DIY projects. Available in multiple sizes (e.g., 10mm–50mm) to accommodate volumes from microsamples to large batches.
