Heathrow Scientific 120548 Magnetic Stir Bar, PTFE, Octagonal, Pivot Ring, 20 x 8 mm, White

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 250°C, making them suitable for use with both unheated and heated stirrers
• Low friction octagon shape with a center pivot ring helps create a strong mixing vortex, even with more viscous solutions
