Heathrow Scientific 120897 Magnetic Stir Bar, PTFE, Smooth, 35 x 8 mm, White, Pack of 10 pcs

Features:

• Magnetic stir bar is made from ALNICO, one of the strongest permanent magnets available
• The sintered manufacturing process reduces the chance of decoupling (spin outs), which weaker stir bars often suffer from
• Encapsulation in PTFE protects both magnet and what it is stirring. Chemically inert and easy to clean
• Can withstand temperatures up to 225°C, allowing for use with both unheated and heated stirrers
• Stir bars are completely smooth, making them ideal to use with concave bottomed glassware
