Description
BOLA 2-way conical stopcock with 6 mm connections is a PTFE laboratory valve for low-pressure tubing or pipe links. The straight-bore two-way body carries two connection ends fitted with nuts made of PTFE-glass fibre, allowing secure attachment of tubes or hoses. A conical plug provides the seal; tightening the conical nut on the underside increases tightness as needed for stable shut-off and flow control in laboratory lines.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.
Because the process medium contacts only PTFE, the stopcock offers universal chemical resistance across typical laboratory reagents and solvents. Bore diameter is 2 mm, the connections are sized for tubing with an outer diameter of 6 mm, and the thread is M 14 × 2. Approximate external dimensions are 59 × 22 × 53 mm (L × D × H); net weight is 0,047 kg. Supplied as one piece, this BOLA fitting from manufacturer Bohlender is intended for analytical benches, pilot circuits and general laboratory manifolds where inert wetted surfaces and simple manual operation matter. The PTFE-glass fibre nuts combine chemical durability with mechanical strength at the connection points, supporting dependable assembly of compact fluid paths without introducing metallic wetted parts into the media stream.

Questions about BOLA 2-Way Stopcocks, Ø 6 mm PTFE, with glass-fibre reinforced PTFE nut
What is this article?
BOLA 2-Way Stopcocks, Ø 6 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.
