These stir bars are PTFE (teflon) coated and appropriate for most chemistry applications. The PTFE is highly resistant to corrosion from chemicals. Our stir bar magnets are rated with 2000-3000 gauss.High magnetism ensures good stability and control when using with a magnetic stirrer. They are for general stirring applications.PTFE coating and a strong magnet on the end allows for easy removal of stir bars in solutions.
