Description
BOLA GL reducers GL 32 – GL 18 PTFE/PPS are laboratory thread adapters for secure transitions between GL sizes in chemical and analytical fluid systems. Each unit pairs a black PPS screw cap with a movable PTFE reducing nozzle and an FKM O-ring, forming a reliable step from a GL 32 thread cap to a GL 18 threaded nozzle. The movable nozzle lets vessels be exchanged without first dismantling connected equipment, because tubing and cables cannot twist during the changeover. Only PTFE contacts the process medium, supporting chemically demanding laboratory work. Suitable for hose diameters from 1,6 mm to 10,0 mm, the reducer covers a practical range of laboratory tubing. Supplied as one piece with a net weight of 0,0303 kg, it is built around polytetrafluoroethylene for the wetted parts. These BOLA GL reducers from manufacturer Bohlender suit research and process laboratories that need inert media contact, straightforward vessel interchange, and dependable GL-thread reduction in everyday setups.

Questions about BOLA GL-Reductions, GL 32 - GL 18 PTFE/PPS
What is this article?
BOLA GL-Reductions, GL 32 - GL 18 PTFE/PPS 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.
