Magnetic Bars

Magnetic stirrer bars (also known as 'beads' and 'flea') are tools that rotate and generate stirring action when immersed in a liquid which is placed on a magnetic stirrer plate. These strong magnet bars are coated with polytetrafluoroethylene (PTFE) or a suitable glass material which is chemically inert, hydrophobic and heat and corrosion resistant. They function as vital accessories to the hot plate. They can easily be retrieved/removed from the flask after their usage. These bars are of various sizes ranging from very small to large and different types of shape are available in kits, sets, offered by different brands.

The standard bar is cylindrical and smooth. A pivot ring at the center acts as the point of rotation. This reduces friction and increases the stirring efficiency.A triangular or polygonal shape generates stronger vortex and more turbulence than cylindrical shape bars.Octagonal or egg-shaped bar generates even stronger vortex and turbulence and is more suited for higher rpm.
