Traditional water-cooled condensers waste significant amounts of water, risk water damage, and require complex setups. While waterless condensers address water usage, they often fail to efficiently contain volatile solvents, especially in larger volumes, leading to solvent loss, increased costs, and safety concerns from vapor leaks or over-pressure. This patented stopper system for a waterless glass condenser revolutionizes solvent recovery by combining efficient vapor containment, safety features, and eco-friendly operation. It uses an innovative plug with a built-in pressure relief valve to prevent over-pressure while virtually eliminating solvent losses. The system is lightweight, compact, and cost-effective, addressing the inefficiencies of current waterless designs and providing scalability for different reaction volumes.
