Magnetic Stirrer Bars - L Series

Magnetic Stirrer Bars, Olive Shape – L Series are PTFE-coated stir bars built for smooth, consistent mixing in round bottom flasks, beakers and other glass vessels. The coating shrugs off acids, alkalis and most solvents, so you are not replacing bars every time a reaction turns corrosive.

The olive shape sits at the centre of the design. It rotates cleanly through low to medium viscosity liquids and holds a steadier vortex than a straight bar, with less splashing against the glass. Inside, each bar carries an Alnico magnet core, which keeps a strong, even coupling with your stirrer plate so the bar keeps turning instead of slipping or stalling mid stir.

PTFE also means the bar will not scratch or pit your glassware, and it cleans up fast between uses, which matters if the same flask is running through several reactions in a day.
