Description
BOLA GL 2-way stopcocks with straight bore provide PTFE shut-off control for laboratory tubing systems that use GL connections. This two-way valve has a straight 6 mm bore and two GL 18 threaded ports. The cylindrical plug is designed for good tightness, and flow direction is indicated by a marking on the stopcock. It is specified for operating pressures up to a maximum of 6 bar and is vacuum-capable. Because the medium touches only PTFE, the component offers universal chemical resistance across typical laboratory reagents and solvents. Approximate outer dimensions are 64 × 30 × 45 mm (L × D × H); net weight is 0,067 kg and gross weight 0,08 kg. These BOLA GL stopcocks from manufacturer Bohlender suit applications that need inert, GL-threaded two-way routing with a larger bore than smaller GL 14 variants. Pack size is 1 piece for individual installation in fluid-handling assemblies.

Questions about BOLA GL 2-Way Stopcocks, GL 18, Ø 6 mm PTFE, cylindrical stopcock plug and GL sc
What is this article?
BOLA GL 2-Way Stopcocks, GL 18, Ø 6 mm PTFE, cylindrical stopcock plug and GL sc 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.
