Description
BOLA ground joint/fitting connectors NS 19/26 with hose dimensions 4,0 x 6,0 mm are PTFE laboratory adapters for connecting tubes, hard-walled tubing and temperature sensors to standard conical ground joints. Circulating sealing rings on the ground joint help prevent seizing and improve the seal during repeated assembly. An integrated Combi nut (Safe-Lab) enables simple securing and release of the taper joint without tools. Made from polytetrafluoroethylene (PTFE), the connector is suited to chemically demanding laboratory set-ups where a reliable transition from glassware to tubing is required. The core is NS 19/26 for tubing with inner diameter 4,0 mm and outer diameter 6,0 mm; the through-bore is 5 mm. Each unit is supplied as one piece with a net weight of 0,05 kg and originates from Germany. These fittings from manufacturer Bohlender support clean, secure connections in synthesis, sampling and sensor mounting work where PTFE contact surfaces and a SAFE LAB nut are preferred for handling and joint integrity.

Questions about BOLA Ground Joint Tube Fittings, NS 19/26 Ø 4 x 6 mm PTFE, SAFE LAB, PTFE nut
What is this article?
BOLA Ground Joint Tube Fittings, NS 19/26 Ø 4 x 6 mm PTFE, SAFE LAB, PTFE nut 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.
