Description
BOLA Tandem Magnetic Stirring Bars with block dimensions of 84 × 36 × 36 mm are specialised laboratory stirring elements for controlled magnetic mixing. Each bar uses PTFE-coated magnetic cores of Alnico 5 and offers universal chemical resistance across a broad range of media. A central bore of 12 mm is provided to accept a BOLA bearing pin or a glass bearing pin (sourced via a glassblower), enabling centred, guided rotation in the vessel. The stirring bar measures 110 mm in length with an outer diameter of 24 mm; the recommended pin height is 37 mm. Delivery comprises the tandem magnetic stirring bar without bearing pin, so the unit is intended for combination with a matching pin fixed to the vessel base. The special-form geometry and net weight of 0,616 kg suit preparative and process setups that need reliable magnetic coupling together with chemical inertness. These BOLA components from manufacturer Bohlender integrate into magnetic stirring assemblies where a defined axis of rotation improves mixing stability. Pack size is 1 piece for direct laboratory use.

Questions about BOLA Tandem Magnetic Stirring Bars, LxHxT 84x36x36 mm Dimensions of block: 84 x
What is this article?
BOLA Tandem Magnetic Stirring Bars, LxHxT 84x36x36 mm Dimensions of block: 84 x is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Magnetic stirring bars, inside Stirring, shaking & mixing, in Lab instruments.
A magnetic stirring bar is the magnet coated in PTFE that spins inside a vessel, driven by a stirrer underneath. Length and shape, plain, oval or cross, have to suit the flask. A bar left against a dry glass wall will grind it.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
