Frequently Asked Questions

AI
A stir bar (or flea) is the small, magnet-encased rod placed inside the liquid. A stirrer is the motorized base device that rotates the magnetic field to spin the bar. You often need both for a complete setup.
PTFE (Teflon) coating offers excellent chemical resistance and is non-reactive with most acids and solvents. However, always check compatibility with strong bases or high-temperature applications to ensure the coating remains intact.
Choose a hot plate stirrer if your experiments require heating the liquid while mixing. If you only need agitation at room temperature, a standard magnetic stirrer is more cost-effective and simpler to use.
