Rotary Evaporator Bump Trap, Fritted Disc

This bump trap has an extra coarse fritted disc sealed between the lower inner and top outer joint to prevent the contents of the flask from bumping into the condenser. This is a convenient, space-saving design good for cramped dry boxes, for example. The top outer joint is a 24/40 standard taper. The bottom standard taper inner joint is sized as indicated.
