PTFE Round Stirring Bars

PTFE is a high-molecular-weight compound consisting wholly of carbon and fluorine that is best known for it's non-stick component. Combining the non-stick component with a wide temperature range from cryogenic to 206°C makes for highly desirable lab supplies.

PTFE beakers, bottles, dippers, flasks and a wide variety of stirring bars in stock and ready to ship. PTFE Labware is attacked only by molten alkali metals and by fluorine at high temperatures.

Features:

• Round stirring bars feature… ALNICO V magnetic cores which are one of the most powerful permanent magnet alloys available.
• Round stir bars should not… be stored in a random mass or dropped on a hard surface, especially steel.
• Stir bars should… be stored in pairs to maintain magnetic strength.
• In general…PTFE thickness accounts for 18% of stir bar diameter.
