Description
BOLA laboratory screw joints GL 14 for hose outer diameter 3,0 mm are compact fittings for secure tubing connections in the laboratory. The red screw cap is made from glass-fibre-reinforced ETFE. Inner parts consist of an ETFE clamping ring plus a sealing wedge and sealing plate, both in PTFE; for hose outer diameters below 3 mm an additional O-ring is fitted that does not contact the flow medium. Only PTFE touches the medium, giving very good chemical resistance for fluid transfer and general lab use. Dimensions match hose outer Ø 3,0 mm with GL 14 thread. Offered as a single piece from manufacturer Bohlender, the unit has a net weight of 0,01 kg and a gross weight of 0,011 kg. PTFE wetted surfaces support inert sealing on modular glassware and tubing lines where chemical durability and a clean medium path matter. The GL 14 interface and defined 3,0 mm hose size simplify selection for standardised laboratory setups.

Questions about BOLA Laboratory Screw Joints, GL 14 Ø 3 mm PTFE inner parts, ETFE cap
What is this article?
BOLA Laboratory Screw Joints, GL 14 Ø 3 mm PTFE inner parts, ETFE 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.
