Description
PTFE stirrer plug for standard ground joints 19/26 is a laboratory accessory that guides and seals a stirrer shaft through a ground-glass joint during agitation. Designed for glass joints 19/26 and a shaft diameter of 8 mm, the plug has a length of 65 mm and is machined from chemically resistant PTFE. It supports stable shaft alignment in reaction vessels, flasks and other ground-joint apparatus used with overhead or laboratory stirrers. The inert PTFE surface is suitable for contact with a wide range of solvents and reagents commonly encountered in organic synthesis and process chemistry. Supplied as a single piece weighing 0,050 kg, the component integrates into existing agitator setups without complex adaptation. This PTFE stirrer plug from manufacturer Bohlender belongs to the accessories range for laboratory stirrers and agitators, where reliable joint sealing and low-friction shaft guidance are essential. Dimensions are matched to standard NS 19/26 geometry and an 8 mm shaft, helping maintain a clean, controlled stirring environment. Use it wherever a durable PTFE plug is required between a standard ground joint and a cylindrical stirrer shaft.
This article is part of Magnetic stirrers, in Stirring, shaking & mixing.

Questions about PTFE stirrer plug for standard ground-, glass joints 19/26, for Ø 8 mm, L 65 mm
What is this article?
PTFE stirrer plug for standard ground-, glass joints 19/26, for Ø 8 mm, L 65 mm 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.
