Description
BOLA filling (stirring) balls are solid PTFE spheres with a diameter of approximately 9 mm and a fine, smooth surface. Made entirely from polytetrafluoroethylene, they offer high chemical resistance and a low-adhesion exterior suited to laboratory filling and gentle stirring duties. One pack comprises 100 pieces with a net weight of 0,1 kg, giving a convenient stock quantity for repeated use across vessels and setups. The full-PTFE body remains stable toward many aggressive chemicals and supports clean contact with solvents and process media. Spherical form and defined diameter promote uniform movement and distribution inside flasks, bottles, and similar containers. These balls come from manufacturer Bohlender in the BOLA product line and are aimed at general laboratory material applications that call for inert, durable PTFE media. The fine surface finish facilitates handling and helps limit residue build-up relative to coarser alternatives. They fit research, analytical, and preparative environments where solid PTFE filling or stirring balls of intermediate size are specified.
This article is part of Magnetic stirrers, in Stirring, shaking & mixing.

Questions about BOLA Balls, Ø 9 mm PTFE, with smooth surface, packing unit 100 pieces
What is this article?
BOLA Balls, Ø 9 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.
