Description
BOLA bellows NS 24/29 – NS 24/29 PTFE with pointed folds are flexible ground-joint connectors for laboratory glassware. Made entirely of polytetrafluoroethylene (PTFE), they offer high chemical resistance together with mechanical compliance, permitting angular deflection of up to 120°. Pointed folds and sealing rings on the outside of the ground-joint core help maintain a dependable seal at the cone. Both the sleeve and the core follow European standard NS 24/29. Overall length extends from a minimum of 110 mm to a maximum of 124 mm, allowing limited axial travel while preserving joint alignment. Supplied as one piece with a net weight of 0,062 kg, the bellows suit distillation, reaction and vacuum assemblies in which misalignment or vibration must be absorbed without stressing fragile glass. These BOLA components from manufacturer Bohlender are practical accessories wherever PTFE inertness and standard ground-joint compatibility are required, reducing mechanical load transfer into the apparatus.

Questions about BOLA Bellows, NS 24/29 - NS 24/29 PTFE, with sharp folds
What is this article?
BOLA Bellows, NS 24/29 - NS 24/29 PTFE, with sharp folds is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
