Bel-Art Spinbar Stir Bar Polyg 25X8MM F371200025

Bel-Art Spinbar Stir Bar Polyg 25X8MM F371200025. Stirring blades have multifaceted surfaces which produce a vortex-like effect and mixes. This effect is critical in aeration and mixing reactions whereby the concentration of a solution or its components are low. Smaller, smoother cylindrical bars do not offer this type of surface area. Bel-Art stir bars have a unique geometry which provides the tightest radial packing of any magnetic stirring bars. In addition, the polygonal shape of the stirring bars provides the highest chemical resistance to etching or clogging. The addition of a number of smaller bars with a small percentage of grooves also increases surface area and thus the reaction speed, thereby giving the equivalent of a tenth of the stirring intensity of a much larger cylindrical bar. The addition of small stir bars to already small volumes increases reaction rates and so the volume of a reaction is usually higher with a given bar diameter.
