Description
BOLA 2-way conical stopcocks with a 10 mm connection diameter are PTFE laboratory valves intended for controlled transfer of chemically demanding media. The straight-bore configuration offers two ports equipped with PTFE-glass fibre nuts for firm attachment of tubes or hoses. Sealing is achieved by a conical stopcock plug; tightening the conical nut from below raises contact pressure and improves tightness without secondary gaskets. Only PTFE touches the flowing medium, delivering universal chemical resistance for routine and specialised laboratory work. This 2-way model features a 5 mm bore diameter, an M 18 x 2 connecting thread, and approximate outer dimensions of 74 x 35 x 69 mm (L x D x H). It accepts tubing with an outer diameter of 10 mm and has a net weight of 0,13 kg. Offered as one piece from manufacturer Bohlender, the stopcock is well matched to setups that require inert wetted parts, straightforward mechanical adjustment of seal force, and dependable two-way shut-off in research, quality control, or process development environments.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about BOLA 2-Way Stopcocks, Ø 10 mm PTFE, with glass-fibre reinforced PTFE nut
What is this article?
BOLA 2-Way Stopcocks, Ø 10 mm PTFE, with glass-fibre reinforced PTFE nut 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.
