Description
BOLA cylindrical magnetic stirring bars measuring approximately 30 mm in length and 6 mm in diameter provide a compact standard solution for laboratory mixing applications. An Alnico 5 magnetic core is completely enclosed in a polytetrafluoroethylene (PTFE) coating, delivering universal chemical resistance across aqueous and organic media commonly encountered in chemical, biological and analytical work. The cylindrical round-rod form ensures steady spinning behaviour on conventional magnetic stirrers and combination hotplate units, helping maintain homogeneous suspensions or solutions in a variety of glassware. At a net weight of 0,003 kg the bars are lightweight yet magnetically effective, and they can be recovered quickly with a magnetic retrieval rod. Manufactured by Bohlender within the BOLA range, these stirring bars offer an inert, easy-to-clean outer surface together with durable magnetic performance for daily laboratory use. They suit routine sample preparation, reaction support and teaching environments where chemical inertness and reliable agitation are essential. Each unit is supplied as one piece, ready for immediate integration into research benches, quality-control stations or production-support laboratories requiring consistent stir-bar performance.

Questions about BOLA Cylindrical Magnetic Stirring Bars, L 30 mm Ø 6 mm PTFE-coated
What is this article?
BOLA Cylindrical Magnetic Stirring Bars, L 30 mm Ø 6 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.
