Description
BOLA glass magnetic stirring bars feature a cylindrical Alnico 5 magnetic core coated with borosilicate glass 3.3 for laboratory mixing applications that benefit from an extremely smooth, pore-free surface. The glass overcoat is described as trace-neutral and helps prevent the accumulation of interfering residues, while still offering universal chemical resistance. Nominal dimensions are approximately 20 mm length and 8 mm diameter in a round rod form that couples cleanly with standard magnetic stirrers. The smooth glass exterior supports work where residue pickup on conventional coatings would be undesirable, including sensitive sample handling and general wet-chemistry agitation. Pack size is 3 pieces, with a net weight of 0,004 kg per bar. These BOLA glass-coated stirring bars from manufacturer Bohlender provide a compact cylindrical option for flasks and vessels matched to the 20 mm length. Construction is limited to the stated Alnico 5 core and borosilicate glass 3.3 coating, with no further purity or sterility claims attached to the product data.

Questions about BOLA Glass Magnetic Stirring Bars, L 20 mm, Ø 8 mm GLASS-coated
What is this article?
BOLA Glass Magnetic Stirring Bars, L 20 mm, Ø 8 mm GLASS-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.
