The magnetic stir bar withstands temperatures up to 250°C, making them suitable for use with both unheated and heated stirrers. The Stir Bar Retriever is encapsulated in PTFE making it easy to clean and durable.

• 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
• The stir bar retriever even works in hot solutions when stirring and mixing is no longer required
