Description
BOLA ground joint adapter NS 19/26 – NS 14/23 is a PTFE laboratory adapter for connecting glassware with different standard ground joint sizes. Made entirely of polytetrafluoroethylene (PTFE), it combines a core NS 19/26 with a socket NS 14/23 and carries sealing rings on the outside for a secure fit. A knurled handle with 30 mm diameter aids grip during assembly and disconnection. Net weight is 0,02 kg. This reducing transition piece from manufacturer Bohlender is intended for routine laboratory glassware setups where chemically inert PTFE and standard ground joints are required. The socket-in-core geometry supports compact installation between apparatus of unequal joint sizes. Supplied as 1 pc, the adapter suits chemical, analytical and general laboratory work involving Normschliff connections. Its PTFE construction provides the material resistance expected for demanding glassware interfaces without introducing metallic components. Use it wherever a reliable NS 19/26 to NS 14/23 PTFE ground joint transition is needed in the fume hood or on the bench.

Questions about BOLA Ground Joint Adapters, NS 19/26 - NS 14/23 PTFE, with standard ground joint
What is this article?
BOLA Ground Joint Adapters, NS 19/26 - NS 14/23 PTFE, with standard ground joint 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.
