2mag Stirring Bars & More

2mag Stirring Bars and Retrievers are an essential component of 2mag Stirring Systems. Our large variety of sizes, shapes, and materials are sure to meet the needs of your laboratory applications. The 2mag Stirring Bars selection includes AlNiCo and SamCo (rare earth) cores; PTFE, ZEDEX, glass, and color-coded coatings; and much more! 

Various stirring bar sizes, shapes, and materials create different stirring effects and can positively or negatively affect the stirring result. For example, the size and shape of the stirring bar influences the resulting vortex. Also, the drive magnet type, vessel shape, liquid viscosity, and solution abrasiveness should all be considered when choosing a stirring bar in order to achieve effective, efficient stirring results. Thus, selecting the ideal stirring bar for a particular laboratory application will vary and may sometimes require experimenting with multiple options.

Don’t forget a 2mag Stirring Bar Retriever to make stirring bar retrieval convenient. Check out our selection, and add 2mag Stirring Bars and Retrievers to your cart today!
