Description
Stirring bar 3,8 cm with rotatable ring, PTFE is a magnetic stir bar designed for reliable mixing in laboratory vessels. Measuring 3,8 cm in length and fully encapsulated in PTFE, it features a rotatable ring that improves stirring performance and reduces friction against the vessel bottom. The chemically inert PTFE coating ensures broad compatibility with aqueous and organic media while protecting the internal magnet from corrosion. Supplied as a pack of five pieces, these bars are suitable for use with hotplate stirrers and magnetic stirrers in routine sample preparation, dissolution and reaction work. This stirring bar from manufacturer Ohaus belongs to the hotplates and stirrers accessories range and offers consistent magnetic coupling for smooth, vortex-free agitation. The compact size makes it ideal for small to medium flasks and beakers commonly found in analytical and research laboratories. Net weight of the pack is 0,5 kg, providing a convenient stock of durable, easy-to-clean stir bars for daily laboratory operations.

Questions about Spinbar 3.8 cm with Pivot Ring PTFE
What is this article?
Spinbar 3.8 cm with Pivot Ring PTFE is the article on this page. Luminix Health distributes Ohaus 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.
