Description
BOLA Tablet magnetic stirring bars with a diameter of approximately 58 mm and a height of approximately 15 mm offer a larger tablet-format option for magnetic mixing in laboratory vessels. The magnetic core is Alnico 5 and is completely covered by a polytetrafluoroethylene (PTFE) coating, delivering universal chemical resistance for use with many laboratory chemicals and solvents. The special tablet shape combines a broad contact area with a low profile, supporting stable rotation on magnetic stirrers and straightforward handling after the run. Net weight is 0,06 kg, matching the more substantial diameter of this variant. Available as one piece from manufacturer Bohlender, the bar fits standard laboratory practice for PTFE-coated magnetic stir bars and stir fleas in research, quality control, and preparative work. Diameter, height, PTFE encapsulation, and Alnico 5 core define a durable stirring accessory for chemically demanding environments where inert surfaces and dependable magnetic coupling are essential.

Questions about BOLA Star Head Magnetic Stirring Bars, Ø 58 mm H 15 mm PTFE-coated
What is this article?
BOLA Star Head Magnetic Stirring Bars, Ø 58 mm H 15 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.
