Description
Three-way stopcock/T-bore with PTFE plug NS 14,5/2,5 mm bore is a laboratory valve constructed from borosilicate glass 3.3. The design includes a T-bore and a PTFE plug featuring a 2,5 mm bore, with the ground joint sized at NS 14,5. This enables connection to compatible glassware in laboratory settings. Available as 1 pc(s) with a net weight of 0,050 kg, the stopcock comes from manufacturer Rettberg and bears the Rettberg ® registered trademark. Originating from Germany, it falls under the product type of valves and is suited for use as a conical stopcock or shut-off valve. Laboratory professionals employ three-way stopcocks of this type to manage the direction of fluids in experimental setups involving chemical reactions or separations. The borosilicate glass 3.3 body is paired with the PTFE plug for the T-bore functionality. Such fittings are standard in scientific glass apparatus for controlling flow paths with the T-configuration allowing multiple routing options.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Stopcock/T-bore, PTFE- plug size 14,5/2,5 mm bore
What is this article?
Stopcock/T-bore, PTFE- plug size 14,5/2,5 mm bore is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
