Kontes* Rotary Evaporator Traps

Design provides for expanded volume for organic mixtures that have a tendency to foam excessively. Inner vapor tube is ring-sealed at the top of the flask to prevent entry into the condenser. Use inner vapor tube at bottom where foaming is likely to occur and be drawn into condeser. The modified joint features a square bead for better sealing to rotary equipment. Top outer TS 24/40 joint on each flask.
