Description
BOLA Star magnetic stirring bars measuring approximately 30 mm in length, 30 mm in width and 12 mm in height are PTFE-coated laboratory stirrers designed for magnetic mixing. Each bar features an Alnico 5 magnetic core fully encapsulated in PTFE, delivering universal chemical resistance for diverse laboratory media. The star geometry aids stable rotation and efficient turbulence generation on conventional magnetic stirrers. Approximate dimensions are length × width 30 × 30 mm with a height of about 12 mm, providing a larger star profile for vessels that require stronger agitation. These stirring bars are supplied in a pack of 3 pieces and have a net weight of 0,013 kg. Offered by manufacturer Bohlender as part of the BOLA line, they address routine stirring needs in chemical, analytical and general laboratory practice. The PTFE surface protects the magnetic core and supports straightforward cleaning between runs. Robust yet chemically versatile, the bars suit homogeneous mixing of solutions in beakers and comparable containers. Their dimensions and star form make them suitable laboratory consumables where reliable magnetic coupling and broad solvent compatibility are essential for day-to-day experimental work.

Questions about BOLA Star Magnetic Stirring Bars, L 30 x B 30 x H 12 mm PTFE-coated
What is this article?
BOLA Star Magnetic Stirring Bars, L 30 x B 30 x 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.
