Description
BOLA laboratory screw joint HT for GL 45 is configured for hose with an outer diameter of 30,0 mm, enabling secure fluid connections on standard laboratory glassware. Its black screw cap is moulded from PPS glass fibre; the internal parts include a PPS clamping ring plus a sealing wedge and sealing plate manufactured from PTFE. For hose outer diameters smaller than 3 mm an extra FKM O-ring is provided without contacting the process medium. Chemical resistance remains high because the medium is exposed solely to PTFE. This laboratory screw joint from manufacturer Bohlender is intended for GL 45 necks on bottles, vessels and transfer systems where inert sealing and mechanical stability are essential. The PPS outer components supply structural strength while the PTFE seals maintain media purity. Offered as one piece with a net weight of 0,085 kg, the fitting is ready for use in research and production laboratories that require a reliable 30,0 mm hose connection on the GL 45 thread standard.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about BOLA HT Laboratory Screw Joints, GL 45 Ø 30,0 mm Glass-fibre reinforced PPS cap
What is this article?
BOLA HT Laboratory Screw Joints, GL 45 Ø 30,0 mm Glass-fibre reinforced PPS cap 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.
