Description
BOLA cylindrical magnetic stirring bars, length approximately 3 mm and diameter approximately 3 mm, are standard laboratory stir bars for reliable mixing in small vessels. Each bar contains an Alnico 5 magnetic core fully encapsulated in a polytetrafluoroethylene (PTFE) coating that offers universal chemical resistance across a broad range of solvents and reagents. The round cylindrical profile supports smooth rotation on magnetic stirrers and steady performance in research and analytical work. Pack size is 10 pc(s), making these compact bars practical for micro-scale and small-volume setups where space is limited. With a net weight of 0,001 kg, they remain lightweight yet robust under typical laboratory conditions. The PTFE overcoat shields the magnetic core while staying inert toward aggressive chemicals, so the bars suit chemistry, life-science and quality-control laboratories that need dependable, chemically resistant stirring elements. Dimensions of about 3 mm length and 3 mm diameter place them in the compact BOLA cylindrical range from manufacturer Bohlender for everyday magnetic stirring tasks in glassware and reaction vessels.

Questions about BOLA Cylindrical Magnetic Stirring Bars, L 3 mm Ø 3 mm PTFE-coated
What is this article?
BOLA Cylindrical Magnetic Stirring Bars, L 3 mm Ø 3 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.
