Beschrijving
Vacuum manifold with 3 PTFE HV valves with fine thread is a glass distribution manifold for vacuum and inert-gas lines in Schlenk and air-sensitive chemistry. Constructed from borosilicate glass 3.3, the unit incorporates three PTFE high-vacuum valves with fine threads that permit controlled adjustment of the passage from 0 to 8 mm. Connection olives of Ø 10 mm provide secure attachment points for vacuum tubing or inert-gas supply. With a net weight of 1,370 kg, the manifold is a substantial bench-top component designed for multi-port vacuum distribution. This Schlenk apparatus item from manufacturer Rettberg supports parallel evacuation or gas blanketing of several reaction vessels from a single source. The combination of chemically resistant borosilicate glass and PTFE valve stems delivers reliable performance under the high-vacuum conditions typical of organometallic and synthetic laboratories. Originating from Germany and supplied as one complete piece, the manifold integrates into existing Schlenk lines and transfer setups where precise isolation of individual ports is required.

Questions about Vacuum distributor, with 3 PTFE high-vacuum valves, fine thread,
What is this article?
Vacuum distributor, with 3 PTFE high-vacuum valves, fine thread, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Kranen & ventielen, inside Slangen, leidingen & koppelingen, in Labmateriaal.
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.
