Description
BOLA centre-ring magnetic stirring bars with PTFE coating are cylindrical laboratory stirrers for reliable mixing in chemical and analytical work. Each bar contains an Alnico 5 magnetic core fully encapsulated in polytetrafluoroethylene, giving universal chemical resistance toward common laboratory solvents and reagents. Approximate dimensions are 12 mm length and 5 mm diameter, a compact size suited to small vessels and low-volume applications that need controlled agitation.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.
The integral centre ring stabilises rotation and helps keep a steady stirring path on standard magnetic stirrers. The round rod profile glides smoothly over vessel bases. Pack size is 1 piece with a net weight of 0,001 kg. These stirring bars from manufacturer Bohlender support routine sample preparation, dissolution and general mixing where PTFE inertness and dependable magnetic coupling are required. The seamless PTFE overcoat protects the magnetic core while preserving chemical compatibility under typical laboratory conditions.

Questions about BOLA Magnetic Stirring Bars with Pivot Ring, L 12 mm Ø 5 mm PTFE-coated
What is this article?
BOLA Magnetic Stirring Bars with Pivot Ring, L 12 mm Ø 5 mm PTFE-coated 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.
