New developed, high-effective stirring bar, ideal for large mixing volumes, viscous media, stirring over wide distances or for disadvantageous vessel bottoms.More than 4x higher torque transmissible, unbeatableincreased mixing effect in comparison to conventional stirringbars, high energetic and long-term stable magnetic field,no demagnetization effect, concave design for a minimumof bearing surface and reliable rotation, triangular shapefor powerful shear force, better mixing effect at lowerrotation speed.300 percent less PTFE abrasion than comparable round shapestirring bars, significantly higher rotation speed reachable,high quality, even and sealed PTFE cover, FDA-conform,steam sterilizable at 121 degrees C.
