Description
BOLA thread adapter GL 25 / GL 45 with Ø 14,5 mm bore is a straight PTFE thread transition piece with two external GL thread connections. It provides a direct step from external thread GL 25 to external thread GL 45 for laboratory bottle, tubing and apparatus setups that use the GL system. Only PTFE is wetted by the medium, so the adapter offers universal chemical resistance and keeps aggressive solvents, acids and bases away from other materials. The straight geometry keeps the flow path short and the installation compact, which suits modular fluid lines, sample transfer and apparatus reconfiguration in analytical and preparative work. Pack size is 1 pc with a net weight of 0,02 kg, so the part adds minimal mass to glassware or plastic assemblies. From manufacturer Bohlender, this BOLA GL adapter is intended where inert PTFE contact, reliable GL mating and a simple external-to-external transition are required without introducing metallic or elastomeric wetted surfaces into the media path.

Questions about BOLA Thread Adaptor GL, GL 25 / GL 45 Ø 14,5 mm PTFE, 2 x Male Thread
What is this article?
BOLA Thread Adaptor GL, GL 25 / GL 45 Ø 14,5 mm PTFE, 2 x Male Thread is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
