Available in 4 sizes.
Round, cylindrical shape with rare earth power magnets. Ideal for mixing in unique conditions, including more viscous liquids and liquids with higher solid content. PTFE stirring bars offer ultimate performance, long working life, and extreme versatility. PTFE coating features chemical resistance, thermal stability, low friction (with little or no adhesion), and insolubility (with high purity). Rare earth magnets have significantly increased magnetic strength compared to AlNiCo V magnets. Practically totally resistant to demagnetism. Stir more viscous liquids and liquids with higher solid content while obtaining a high stirring speed. Stirring force will be maintained even at greater distances. Inert and leak-free. Isostatic encapsulation to eliminate cracks and porosity. Polished finish to reduce pickup and cross contamination. Can be sterlized via all typical chemical or thermal (i.e., autoclave, etc.) means (except gamma radiation). FDA and USP Class VI approved PTFE (polytetrafluoroethylene). Pure PTFE coating. Rare earth (i.e., SamCo, samarium-cobalt) magnet core. Various dimensions and weights. See dropdown options to select size. Note: High magnetic coupling power of stirring bar using rare earth magnets may cause abrasion of PTFE coating against base of container (this does not apply to tripod stirring bars) and, where stirring arrays are used, such as in multi-well plates, lateral interaction between stirring bars may be observed. Small stirring bars using rare earth magnets are identified by a carbon black spot, which is chemically inert.
