Description
Drain cock 3/4'' with an inner diameter of 19 mm is a compact outlet fitting for controlled emptying of compatible laboratory storage bottles and containers. The 3/4'' thread mates with vessels prepared for this connection, enabling gravity discharge or metered draw-off of aqueous media, buffers and process liquids without tipping the full container. Inner bore of 19 mm supports a practical flow rate for routine laboratory and pilot-scale handling while remaining easy to clean. Designed for use with bottle types EG-330, EG-1190, EG-1191 and EG-1192, the cock completes wide-neck HDPE storage systems that are supplied without a tap. From manufacturer lab-o-plastix, the accessory is offered as a single piece for straightforward retrofit or spare replacement on matching threaded outlets. Integrating a dedicated drain cock improves ergonomics and spill control during media transfer, sampling and vessel emptying in production, quality-control and general laboratory workflows where reliable bottom discharge is preferred over pouring from large containers.

Questions about Stopcock 3/4'' inside Ø 19 mm
What is this article?
Stopcock 3/4'' inside Ø 19 mm is the article on this page. Luminix Health distributes lab-o-plastix 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.
