Description
BOLA Cross Magnetic Stirring Bars (L×W×H 38×38×15 mm) are PTFE-encapsulated magnetic stirrers for dependable mixing under chemically aggressive conditions. A cross-shaped body houses an Alnico 5 magnetic core, ensuring strong magnetic coupling, while the continuous polytetrafluoroethylene (PTFE) coating offers universal chemical resistance to solvents, acids and bases commonly encountered in the laboratory. Approximate dimensions are 38 mm length by 38 mm width and 15 mm height, providing a slightly larger contact area for medium-volume flasks and beakers. The cruciform geometry supports effective vortex formation and helps maintain stable rotation. Offered in packs of three pieces from manufacturer Bohlender, the bars suit sample preparation, reaction work-up and general laboratory stirring tasks. Net weight is 0,019 kg per unit. Country of origin is Great Britain. Choose these PTFE cross bars wherever inert, chemically resistant magnetic stirring elements are needed.

Questions about BOLA Crosshead Magnetic Stirring Bars, LxBxH 38x38x15 mm PTFE - coated
What is this article?
BOLA Crosshead Magnetic Stirring Bars, LxBxH 38x38x15 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.
