Description
BOLA filling (stirring) balls are solid PTFE spheres with a diameter of approximately 6 mm and a fine, smooth surface finish. Manufactured entirely from polytetrafluoroethylene, they combine chemical inertness with a low-friction exterior that suits demanding laboratory handling. Each pack contains 100 pieces and has a net weight of 0,04 kg, providing a practical quantity for routine vessel filling, mixing support, or gentle agitation tasks. The full-PTFE construction resists aggressive media and helps minimise contamination risk when balls contact solvents, reagents, or process fluids. Their compact spherical geometry supports even distribution in flasks, bottles, and other containers where free-moving media are preferred. Supplied from manufacturer Bohlender under the BOLA range, these balls are intended for general laboratory material use where durable, chemically stable PTFE components are required. The fine surface finish aids clean handling and reduces adhesion of residues compared with rougher media. Suitable for filling and stirring applications in research, quality control, and preparative workflows that benefit from inert solid spheres of defined size.
This article is part of Magnetic stirrers, in Stirring, shaking & mixing.

Questions about BOLA Balls, Ø 6 mm PTFE, with smooth surface, packing unit 100 pieces
What is this article?
BOLA Balls, Ø 6 mm PTFE, with smooth surface, packing unit 100 pieces is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Magnetic stirrers, inside Stirring, shaking & mixing, in Lab instruments.
A magnetic stirrer is the motor and the plate under the flask. Many also heat. The stirring capacity is the litres of a water-like liquid it can turn, and a viscous liquid defeats a rating that was measured on water.
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.
