Rare Earth Magnetic Stir Bar, Octahedral PTFE, 25 x 8mm

This octahedral-shaped, top quality magnetic spin bar features a Rare Earth Neodymium magnetic core, assuring extremely high strength magnetization coupled with almost total resistance to demagnetization. The inert nonstick PTFE coating resists harsh chemicals, is resistant to scratching and high temperatures. Its oval shape reduces friction and increases effectiveness in round-bottom flasks.
