0,00$Price
Features
- 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
- Low friction octagon shape with a center pivot ring helps create a strong mixing vortex, even with more viscous solutions
- The stir bar retriever can recover stir bars even in hot solutions when stirring and mixing is no longer required
