Description
BOLA filling (stirring) balls are solid PTFE spheres with a diameter of approximately 3 mm and a smooth, fine surface finish. Designed for laboratory filling and stirring duties, these inert polymer balls support gentle mixing and volume displacement in glassware and process vessels where metal media would be unsuitable. Full-PTFE construction provides broad chemical resistance and a non-stick character that helps keep residues low during repeated use. Each pack contains 100 pieces, giving a practical stock quantity for routine lab workflows. With a net weight of only 0,004 kg per pack, the spheres remain light and easy to handle when loading or recovering media. Manufactured by Bohlender, the BOLA range is well established for fluoropolymer laboratory components. Typical applications include filling voids, aiding agitation in flasks, and protecting sensitive surfaces during stirring operations. The compact 3 mm size suits narrow necks and smaller reaction setups while remaining simple to separate after use. These balls are intended for general laboratory material handling rather than analytical reagents, and their PTFE body supports use across many common organic and aqueous media.

Questions about BOLA Balls, Ø 3 mm PTFE, with smooth surface, packing unit 100 pieces
What is this article?
BOLA Balls, Ø 3 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.
