Description
BOLA ground-joint GL 2-way stopcocks combine an NS 29/32 ground joint with a GL 18 threaded port and a straight 6 mm bore, all fabricated from polytetrafluoroethylene (PTFE). The two-way configuration uses a cylindrical stopcock plug for dependable sealing and includes a flow-direction marking on the handle for unambiguous operation. Rated for pressures up to a maximum of 6 bar and suitable for vacuum service, the valve keeps the process medium in contact solely with PTFE, delivering universal chemical resistance in laboratory fluid paths. Approximate external dimensions are 100 × 40 × 57 mm (L × D × H) with a net weight of 0,118 kg. These stopcocks from manufacturer Bohlender integrate directly into glass apparatus via the NS 29/32 joint while the GL 18 side accepts compatible tubing or fittings. Typical uses include controlled transfer, isolation and sampling of aggressive or high-purity media where metal-free wetted surfaces are essential. Pack size is one piece for apparatus build-up or replacement.

Questions about BOLA Ground Joint-GL 2-Way Stopcocks, GL 18, NS 29/32, Ø 6 mm PTFE, cylindrical
What is this article?
BOLA Ground Joint-GL 2-Way Stopcocks, GL 18, NS 29/32, Ø 6 mm PTFE, cylindrical is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
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.
