Description
Bottom drain valve for reaction vessel DN100 is a laboratory glassware component designed for controlled emptying of reaction vessels fitted with a bottom outlet. It combines a KS 40/25 shell interface with a stopcock ground joint NS 18,8/6, enabling secure attachment and precise flow regulation during synthesis, work-up or cleaning steps. The nominal diameter DN100 matches standard reaction-vessel bottom ports used in preparative and process chemistry. Supplied as a single piece with a net weight of 0,086 kg, the valve supports reliable drainage without compromising vessel integrity. Manufactured by Witeg, this bottom outlet cock is intended for integration into glass reaction systems where a dedicated drain path is required. Typical applications include organic synthesis setups, multipurpose reactors and pilot-scale glass apparatus that need a dedicated bottom discharge route. The compact design keeps dead volume low while the standardised joints ensure compatibility with common laboratory glassware. Ideal for laboratories seeking a dedicated DN100 bottom drain solution for reaction vessels.

Questions about Stopcocks for bottom outlet for reactio
What is this article?
Stopcocks for bottom outlet for reactio is the article on this page. Luminix Health distributes Witeg 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.
