Description
High-vacuum straight-through valve, 0 – 10 mm, with PTFE spindle is a precision laboratory component engineered for reliable shut-off and flow control in high-vacuum apparatus. Manufactured from borosilicate glass 3.3 with a fine-thread PTFE spindle, it offers an adjustable passage ranging from 0 to 10 mm. The tube connections feature an outer diameter of 13 mm, enabling secure integration into existing glass vacuum lines and manifolds. Net weight is 0,059 kg, keeping the unit light enough for multi-valve assemblies. The combination of borosilicate glass and PTFE delivers chemical resistance and grease-free sealing for a broad range of laboratory reagents. This high-vacuum straight-through valve from manufacturer Rettberg suits distillation systems, Schlenk techniques and analytical vacuum setups in research and process laboratories. Its straight-through design reduces flow resistance and dead space, contributing to stable vacuum performance in chemistry and materials-science applications.

Questions about High vacuum valve, straight, 0 - 10 mm, with PTFE-spindle,
What is this article?
High vacuum valve, straight, 0 - 10 mm, with PTFE-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.
Which category should I open next?
