Details

Here is the corrected and rephrased product description: Octagon Magnetic Stirring Bars with Integral Pivot Ring are the most commonly used shape. These bars feature an Alnico magnet encapsulated in FDA-grade, USP Class VI Teflon PTFE low-friction coating, which is durable and inert. The interrupted profile of these bars provides greater surface area and added turbulence compared to smooth cylindrical bars, while the pivot ring aids in reducing friction and chattering. These stirring bars are available in red, yellow, or blue colors. All stir bars have a pivot ring, except for the 12.7 x 3mm sizes (58949-044, -046, and -050). They are also autoclavable. Manufactured in a registered ISO 9001:2008 facility, as verified by SGS certification, these stirring bars offer high-quality performance. An assortment of six different sizes is available, with two each of red, yellow, and blue colors.
