Description
High-vacuum stopcock in angle form with hollow glass key NS 14,5/2,5 mm bore is a compact laboratory valve engineered for high-vacuum applications. Made from borosilicate glass 3.3, it features right-angled limbs and a hollow glass plug that ensure dependable sealing and precise flow control. The NS 14,5 joint paired with a 2,5 mm bore suits smaller vacuum lines, manifold branches and specialised glass apparatus where space and controlled conductance are important. Delivered as a single piece weighing 0,053 kg, the stopcock is easy to incorporate into existing setups. Borosilicate glass 3.3 construction confers excellent chemical resistance and thermal stability for everyday laboratory use. This high-vacuum stopcock from manufacturer Rettberg enables reliable isolation and reconnection of vacuum circuits in research and analytical environments. The right-angled geometry reduces footprint and simplifies routing in crowded apparatus, offering chemists and laboratory technicians a durable, high-performance solution for angle-configuration high-vacuum work.

Questions about High vacuum stopcock/right angle, hollow glass plug size 14,5/2,5 mm bore
What is this article?
High vacuum stopcock/right angle, hollow glass plug size 14,5/2,5 mm bore is the article on this page. Luminix Health distributes Rettberg 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.
