Description
Stirring bar 2,5 cm PTFE is a compact magnetic stirring accessory intended for reliable mixing in laboratory vessels used with hotplates and stirrers. Manufactured from chemically resistant PTFE, the bar provides smooth rotation and chemical inertness across a wide range of aqueous and organic media commonly encountered in research and quality-control workflows. The 2,5 cm length suits smaller flasks, beakers and reaction vessels where controlled agitation is required without excessive vortex formation. Supplied as a single piece with a net weight of 0,063 kg and identical gross weight, the unit arrives in compact packaging measuring 0,102 m depth by 0,102 m width by 0,025 m height and a volume of 0,001 m³. Originating from the USA, this accessory belongs to the hotplates and stirrers accessories category and integrates readily into existing magnetic stirring setups. The PTFE construction from manufacturer Ohaus ensures low friction against glass or plastic surfaces while maintaining dimensional stability during prolonged operation. Ideal for routine sample preparation, dissolution studies and general laboratory mixing tasks, the stirring bar offers a straightforward, durable solution for everyday stirring needs in analytical and preparative environments.

Questions about Spinbar 2.5 cm PTFE
What is this article?
Spinbar 2.5 cm 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.
