Description
BOLA Laboratory Screw Joint HT, GL 18, Ø 3,0 mm is a laboratory screw fitting designed for secure connection of tubing in high-temperature laboratory applications. It features a black screw cap of PPS-glass fibre with wrench size SW 22, allowing firm installation with standard tools. The inner assembly consists of a clamping ring made of PPS plus a sealing wedge and sealing plate, both manufactured from polytetrafluoroethylene (PTFE). An additional FKM O-ring is used on variants for hose outer diameters smaller than 3 mm and remains without contact to the flow medium. The process medium therefore contacts only PTFE, providing good chemical resistance. The joint is dimensioned for tubing with an outer diameter of 3,0 mm and a GL 18 thread. Delivered as a single piece with a net weight of 0,018 kg, this BOLA laboratory screw joint from manufacturer Bohlender supports dependable sealing in fluid-handling systems that demand chemical inertness at the wetted surface. PPS structural components combined with PTFE seals make the fitting suitable for routine and demanding laboratory tubing connections on GL 18 ports.

Questions about BOLA HT Laboratory Screw Joints, GL 18 Ø 3,0 mm SW 22 Glass-fibre reinforced PPS
What is this article?
BOLA HT Laboratory Screw Joints, GL 18 Ø 3,0 mm SW 22 Glass-fibre reinforced PPS 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.
