Description
High-vacuum straight-through valve with glass spindle is a precision shut-off component for laboratory vacuum lines. It features a fine thread, a glass spindle and an adjustable passage from 0 to 8 mm, with a tube connection of 11 mm outer diameter. The body is made of borosilicate glass 3.3 and is intended especially for use in low temperature ranges. PTFE sealing elements support reliable operation under high-vacuum conditions. This Rettberg valve is supplied as a single piece with a net weight of 0,049 kg and is suited to straight-through control in vacuum manifolds, glass apparatus and related laboratory setups where fine flow adjustment and vacuum integrity are required. The combination of glass spindle, fine-thread drive and borosilicate construction makes it a practical choice for demanding vacuum work in research and analytical laboratories.

Questions about High vacuum valve, straight, 0-8 mm, with glass spindle
What is this article?
High vacuum valve, straight, 0-8 mm, with glass spindle 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.
