Description
High-vacuum stopcock in one-way form with hollow glass key NS 29/10,0 mm bore is a precision laboratory valve for demanding vacuum work. Fabricated from borosilicate glass 3.3, it combines a hollow glass plug with parallel limbs to deliver reliable sealing and flow control under high-vacuum conditions. The NS 29 joint and 10,0 mm bore offer generous throughput while preserving vacuum integrity in distillation lines, Schlenk apparatus and manifold systems. Supplied as a single piece with a net weight of 0,176 kg, the stopcock integrates readily into existing glassware setups. Its robust borosilicate glass 3.3 construction provides the chemical resistance and thermal stability expected in research and analytical laboratories. This high-vacuum stopcock from manufacturer Rettberg supports controlled isolation and reconnection of vacuum circuits without compromising system performance. The one-way parallel-limb geometry simplifies routing and reduces dead volume, making it a practical choice for chemists and technicians who require durable, high-performance glass stopcocks for routine and specialised high-vacuum applications.

Questions about High vacuum stopcock, hollow glass plug glass plug size 29/10,0 mm bore, strai
What is this article?
High vacuum stopcock, hollow glass plug glass plug size 29/10,0 mm bore, strai 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.
