Description
BOLA filling (stirring) balls are solid PTFE spheres measuring approximately 15 mm in diameter with a fine, smooth surface. Fabricated completely from polytetrafluoroethylene, they deliver chemical inertness and a low-friction finish appropriate for laboratory filling and stirring work. Each pack holds 50 pieces and weighs 0,2 kg net, matching larger ball size with a practical unit quantity. Full-PTFE construction withstands contact with many aggressive reagents and reduces contamination concerns in sensitive setups. The larger spherical geometry is useful where greater mass or spacing of free-moving media is desired inside flasks, bottles, and process vessels. Offered by manufacturer Bohlender within the BOLA range, these balls serve general laboratory material needs that require robust PTFE spheres of defined diameter. The fine surface supports clean handling and limits adhesion of residues. They are suitable for research, quality-control, and preparative applications that specify solid PTFE filling or stirring balls at the 15 mm size class.
This article is part of Magnetic stirrers, in Stirring, shaking & mixing.

Questions about BOLA Balls, Ø 15 mm PTFE, with smooth surface, packing unit 50 pieces
What is this article?
BOLA Balls, Ø 15 mm PTFE, with smooth surface, packing unit 50 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.
