Description
Stopcock for storage bottles in polypropylene (PP) is a practical laboratory fitting designed for controlled dispensing from compatible storage containers. Intended for use with article numbers 81660 through 81666, this stopcock supports orderly liquid handling when bottles must be opened, closed, or drained without unnecessary spillage. Polypropylene construction offers a lightweight, chemically robust polymer choice commonly selected for general laboratory ware that contacts aqueous media and many routine reagents. The component belongs to the drain-cock category and helps organise bench or storage workflows where repeatable on/off control at the bottle outlet is required. Supplied as a single piece, it is straightforward to stock as a spare or replacement part for matching bottle systems. Manufactured by Vitlab, the stopcock integrates into everyday lab logistics for media, buffers, and process liquids held in designated storage bottles. Clear article-number compatibility simplifies ordering and reduces mismatch risk when maintaining multi-bottle setups. Suitable for teaching, research, and quality-control environments that rely on polypropylene bottle accessories for safe, tidy dispensing.

Questions about Tap, PP, for storage bottles narrow-neck
What is this article?
Tap, PP, for storage bottles narrow-neck is the article on this page. Luminix Health distributes Vitlab for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Matériel de laboratoire.
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.
