Description
BOLA GL bellows GL 25 are PTFE laboratory connectors with black PPS screw caps, offering a maximum bellows length in the 100 mm class for larger GL threads. The connecting element is a PTFE bellows with pointed folds, engineered to create a flexible and stress-free joint between GL-threaded components. Two screw caps manufactured from PPS provide the GL thread and are fitted with a PTFE/FKM seal for a reliable, chemically resistant closure. The bellows remains bendable up to an angle of 120°, supporting alignment correction and movement without imposing tension on glassware or tubing. According to the dimensional data, the GL 25 version has a minimum bellows length of 58 mm and a maximum bellows length of 104 mm. Bellows material is polytetrafluoroethylene (PTFE), chosen for inert performance in laboratory environments. Net weight is 0,044 kg per unit, packed as 1 pc. These BOLA GL bellows from manufacturer Bohlender address flexible GL 25 coupling needs where a PTFE bellows with PPS screw caps delivers a tension-free laboratory connection.

Questions about BOLA GL Bellows, GL 25, max. L 100 mm PTFE. Screw caps made of PPS (black), very
What is this article?
BOLA GL Bellows, GL 25, max. L 100 mm PTFE. Screw caps made of PPS (black), very is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
