Adaptors, Rotary Evaporator Bump Traps, R200 & R205

Vapor tube/bump trap adapter is designed to be used with the Büchi® R-200/205 rotary evaporators. This adapter combines a vapor tube adapter and a bump trap. Tapered sidewalls permit continuous washing with condensed solvent, while preventing vapor cooling points along the path of the condenser. The upper stem has 2 large holes flush with the lower end, allowing solvent vapor to flow freely, making this portion of the trap easy to clean. Adapters have a 50mm OD top flange with a tapered interior to fit the Büchi® sealing ring. Lower portion of the adapter has the listed standard taper inner joint. Each adapter is supplied complete with the corresponding size Keck clip.
