Description
BOLA tablet magnetic stirring bars with a diameter of approximately 10 mm and a height of approximately 8 mm are compact laboratory stirrers for reliable magnetic mixing in small vessels. Each bar contains an Alnico 5 magnetic core fully enclosed in a polytetrafluoroethylene (PTFE) coating that offers universal chemical resistance toward a broad range of laboratory media, including aggressive solvents and reagents. The low-profile tablet geometry sits stably on flat vessel bases and supports consistent agitation under standard magnetic stirrers, distinguishing it from conventional elongated stir bars. Supplied in a pack of 3 pieces from manufacturer Bohlender, these stirring bars suit small-volume sample preparation, dissolution work, buffer mixing and general laboratory agitation where an inert PTFE surface is preferred. Net weight is 0,002 kg. The special-form design helps maintain contact with the vessel floor during operation and simplifies retrieval with a magnetic pick-up rod. They form part of the BOLA range of PTFE-coated magnetic accessories used in chemical synthesis, analytical sample work-up and routine media preparation in research and quality-control laboratories.
This article is part of Magnetic stirring bars, in Stirring, shaking & mixing.

Questions about BOLA Star Head Magnetic Stirring Bars, Ø 10 mm H 8 mm PTFE-coated
What is this article?
BOLA Star Head Magnetic Stirring Bars, Ø 10 mm H 8 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.
