Description
BOLA T-screw couplings GL 25 provide a PTFE T-connector with freely rotatable PPS screw caps for linking laboratory GL threads of the same size. The screw caps incorporate a GL thread and a PTFE/FKM seal, while the T-body is manufactured from PTFE, ensuring that only PTFE touches the medium. This design suits chemically aggressive media, solvents and sensitive reagents where an inert flow path is essential. Intended for equal GL thread sizes, the coupling spans 55 mm from sealing lip to sealing lip, offering a robust yet compact branch for larger GL 25 glassware and tubing systems. Net weight is 0,0515 kg. Delivered as a single piece, it installs directly into matching GL 25 setups without intermediate adapters. These BOLA fittings from manufacturer Bohlender support analytical, preparative and pilot-scale work that depends on standardised GL screw connections and needs dependable, metal-free T-junctions for fluid handling and distribution.

Questions about BOLA Threaded Couplings T, GL 25 PTFE, PPS nuts
What is this article?
BOLA Threaded Couplings T, GL 25 PTFE, PPS nuts 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.
