Description
Stopcock, PTFE, one-way with olives, for tubing I.D. 4 mm, bore 2 mm is a laboratory stopcock for manual flow control in flexible tubing systems. The PTFE body provides high chemical resistance for everyday aqueous work as well as many organic solvents and reagents. Olive ends accept tubing with an inner diameter of 4 mm, and the 2 mm bore enables controlled passage of liquids or gases in analytical, synthesis support, and general laboratory installations. Offered as a single piece from manufacturer Brand, this one-way PTFE stopcock with olives is a practical choice for shut-off, routing, and simple isolation tasks where glass valves are less convenient. Approximate net weight is 0,0429 kg, so the component remains light enough for bench assemblies and portable setups. It suits quality-control, research, and teaching environments that standardise on 4 mm I.D. tubing and need inert, easy-to-clean valve surfaces. Integrating this stopcock helps maintain reliable connections and repeatable manual control across reagent lines, wash circuits, and small-scale transfer applications without changing established tubing dimensions.

Questions about Stopcock, PTFE, one-way with nozzles, f. tub. inner dia. 4 mm bore 2 mm
What is this article?
Stopcock, PTFE, one-way with nozzles, f. tub. inner dia. 4 mm bore 2 mm is the article on this page. Luminix Health distributes Brand 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.
