Description
Vacuum manifold with 4 PTFE high-vacuum valves with fine thread is a Schlenk apparatus component for controlled multi-port vacuum distribution in the laboratory. The unit offers a continuous passage from 0 to 8 mm and is fitted with hose connections using olives of Ø 10 mm, allowing straightforward coupling to vacuum tubing and Schlenk glassware. Constructed from borosilicate glass 3.3, it combines chemical resistance with good thermal stability for routine inert-atmosphere and reduced-pressure work. Each of the four PTFE high-vacuum valves incorporates a fine thread for precise flow adjustment across the ports, supporting parallel reactions, solvent transfers and line isolation. Supplied as one piece with a net weight of 1,700 kg, the manifold integrates into existing vacuum and Schlenk setups without additional adapters beyond standard olive tubing. Manufactured by Rettberg and bearing the Rettberg® mark, this German-made distributor is intended for research and synthesis laboratories that require reliable, leak-tight vacuum branching. Typical use cases include organometallic chemistry, air-sensitive handling and multi-line Schlenk systems where independent valve control improves workflow and safety.

Questions about Vacuum distributor, with 4 PTFE high-vacuum valves, fine thread,
What is this article?
Vacuum distributor, with 4 PTFE high-vacuum valves, fine thread, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Matériel de laboratoire.
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.
