Description
BOLA Tandem Magnetic Stirring Bars are PTFE-coated special-form stirrers built around Alnico 5 magnet cores for chemically demanding laboratory mixing. A central bore accepts a BOLA bearing pin or a glass bearing pin (glass pin sourced separately via a glassblower), allowing guided tandem operation when a fixed pivot is required. The stirring element measures 40 mm in length by 10 mm outer diameter, with an 8 mm bore for the bearing pin and a recommended pin height of 15 mm. Block dimensions are 34 x 14 x 14 mm. Universal chemical resistance of the PTFE encapsulation supports use across a wide range of solvents and reagents. The unit is supplied without a bearing pin, so the pin can be selected to match the vessel geometry. Net weight is 0,0306 kg. This compact tandem design from manufacturer Bohlender is intended for applications where a guided magnetic stirrer improves stability compared with free bars. Pack size is one piece for laboratory stirring setups needing PTFE-protected Alnico cores and a defined block geometry.

Questions about BOLA Tandem Magnetic Stirring Bars, LxHxT 34x14x14 mm Dimensions of block: 34 x
What is this article?
BOLA Tandem Magnetic Stirring Bars, LxHxT 34x14x14 mm Dimensions of block: 34 x is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Magnetic stirring bars, inside Stirring, shaking & mixing, in Lab instruments.
A magnetic stirring bar is the magnet coated in PTFE that spins inside a vessel, driven by a stirrer underneath. Length and shape, plain, oval or cross, have to suit the flask. A bar left against a dry glass wall will grind it.
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.
