Description
BOLA tablet magnetic stirring bars, approximately 35 mm in diameter and 12 mm in height, are PTFE-coated laboratory stirring elements for magnetic mixing applications. Each bar incorporates an Alnico 5 magnetic core fully encapsulated in polytetrafluoroethylene (PTFE), giving universal chemical resistance in contact with a wide range of laboratory reagents. The special tablet geometry provides a stable stirring profile on magnetic stirrers, and the smooth PTFE surface helps minimise residue build-up and simplifies cleaning. Net weight is 0,015 kg per piece, appropriate for vessels that require a larger-diameter tablet form and consistent agitation. Available as a single piece from manufacturer Bohlender, this BOLA stirring bar is suited to dissolution work, sample preparation and everyday laboratory mixing. The PTFE coating protects the magnetic core and maintains chemical inertness under repeated exposure to aggressive media. Dimensions of about 35 mm diameter and 12 mm height define a low-profile tablet that rests securely on the vessel base for effective magnetic coupling. Durable PTFE construction and universal chemical resistance support reliable performance in chemistry and analytical laboratory environments.

Questions about BOLA Star Head Magnetic Stirring Bars, Ø 35 mm H 12 mm PTFE-coated
What is this article?
BOLA Star Head Magnetic Stirring Bars, Ø 35 mm H 12 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.
