Description
BOLA cylindrical magnetic stirring bars with a length of approximately 8 mm and a diameter of approximately 2 mm are standard laboratory stir bars built around a PTFE-coated Alnico 5 magnetic core. The round rod geometry promotes steady rotation and effective mixing in small- to medium-volume vessels. The polytetrafluoroethylene (PTFE) coating delivers universal chemical resistance, shielding the magnet while remaining compatible with a broad spectrum of laboratory chemicals and solvents. An Alnico 5 core provides dependable magnetic response on standard magnetic stirrers. This variant is supplied as 10 pc(s), with each bar having a net weight of 0,001 kg, and comes from manufacturer Bohlender under the BOLA range. Approximate dimensions of 8 mm length and 2 mm diameter suit general mixing applications in research, quality control, and analytical laboratories where an inert contact surface is required. The PTFE overcoat supports smooth, low-friction spinning and helps protect sample integrity. Country of origin is Great Britain. These standard cylindrical BOLA stirring bars offer consistent form and chemical resistance for routine laboratory use.

Questions about BOLA Cylindrical Magnetic Stirring Bars, L 8 mm Ø 2 mm PTFE-coated
What is this article?
BOLA Cylindrical Magnetic Stirring Bars, L 8 mm Ø 2 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.
