Essential equipment for air- and moisture-sensitive chemistry, Schlenk lines enable controlled manipulation of reagents under inert gas or vacuum. Commonly used in organometallic and synthetic chemistry, they allow rapid switching between vacuum and inert gas to maintain oxygen- and moisture-free conditions. Designed with multiple ports, taps, and valves, Schlenk lines support safe evacuation, purging and gas transfer. Compatible with standard laboratory glassware and vacuum systems, they are indispensable in research, industrial and advanced teaching laboratories.
