A vacuum manifold lets you switch a flask between vacuum and inert gas without exposing its contents to air. That makes it the core tool for handling moisture- and oxygen-sensitive reagents, running air-free reactions, and drying samples under vacuum.  

A Schlenk line is a specific type of vacuum manifold: a dual bank design with one tube on vacuum and one on inert gas, so you can select either service for any port. Single bank manifolds connect to one source at a time. Every dual bank manifold in this range is a Schlenk line. 

Choose dual bank if you need vacuum and inert gas live on the same line at once, which is typical for air-sensitive synthesis. Choose single bank for evacuation and backfilling, sample drying, or any workflow where switching the whole line between services is fine  

Greaseless PTFE valves don't introduce stopcock grease into your line, which protects sensitive reactions from contamination. They also hold a consistent high-vacuum seal and use replaceable O-rings, so a worn seal is a serviceable part rather than a reason to replace the valve. We do offer a glass stopcock dual bank model for labs that prefer ground-glass stopcocks

Pick for the number of vessels you run at the same time, with a little headroom. Our manifolds range from 3 to 8 ports. Remember that more ports mean a wider manifold, so confirm it fits your fume hood  

Yes. The single bank gauge-port model has a vacuum gauge port built in. The standard dual bank manifold can take an NW16 flange to connect a gauge (look for the -NW16 product codes).  

One bank connects to a vacuum pump, usually through a cold trap that keeps solvent vapors out of the pump. The inert gas bank connects to a nitrogen or argon supply, typically vented through an oil bubbler to maintain a slight positive pressure. The manifold is the control point between your vessels and those two services

The HP valve is an upgraded J. Young PTFE valve with a more robust design, a reinforced sealing area, and improved interchangeability, intended for more demanding applications. It's available in both fine and fast thread across the PTFE-valve models
