Description
BOLA bolts and expansion discs are complete PTFE fastening elements for stirrers with double blades, linking the stirrer shaft to the stirring blade while keeping the blade freely rotatable. Each bolt includes a spacer that maintains the correct distance between shaft and blade so rotation is never restricted during use. Specified dimensions are bolt diameter 8 mm, usable length 12 mm, and suitability for stirring-blade bore diameter 8,5 mm. The components are made entirely of polytetrafluoroethylene (PTFE), giving the chemical inertness and low-friction behaviour typical of fluoropolymer laboratory hardware. These BOLA parts from manufacturer Bohlender belong to the centrifugal-stirrer accessory range and support all-plastic assemblies where metal fasteners are undesirable. They are supplied in a pack of 5 pc(s) with a net weight of 0,003 kg. Clear matching of bolt diameter, usable length and blade bore simplifies correct installation on compatible double-blade stirrers in chemical and process laboratories that require PTFE construction throughout the connection.
This article is part of Magnetic stirrers, in Stirring, shaking & mixing.

Questions about BOLA Bolts and Clamp Rings, Ø 8 mm L 12 mm Ø 8,5 mm PTFE, double long-groove key
What is this article?
BOLA Bolts and Clamp Rings, Ø 8 mm L 12 mm Ø 8,5 mm PTFE, double long-groove key 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.
