Description
Magnetic stirring bar octagon, PTFE 10 x 25 mm is a precision laboratory stirring element for efficient mixing on magnetic stirrers. Fabricated from polytetrafluoroethylene (PTFE), the bar has a diameter of 10 mm and a length of 25 mm in a distinctive octagonal profile that generates strong turbulence and reliable fluid movement. The chemically inert PTFE construction resists aggressive solvents, acids and bases, making the bar suitable for chemistry, biology and analytical workflows. Supplied in a convenient pack of 10 pieces from manufacturer Vitlab, these stirring bars maintain consistent performance across repeated use cycles. The octagonal geometry improves coupling with the drive magnet and reduces spinning out at higher speeds compared with smooth cylindrical designs. Compact dimensions allow use in small to medium vessels such as beakers, Erlenmeyer flasks and reaction tubes. Researchers benefit from low residue adhesion and easy cleaning after experiments. This stirring bar supports reproducible sample preparation, dissolution and reaction monitoring under standard laboratory conditions.

Questions about Magnetic stirring-bar, PTFE, OCTAGON, 10 x 25 mm, with pivot ring
What is this article?
Magnetic stirring-bar, PTFE, OCTAGON, 10 x 25 mm, with pivot ring is the article on this page. Luminix Health distributes Vitlab 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.
