Rotary Evaporator Bump Traps, Fritted Disc

These bump traps have 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 available in 14/20, 24/40 or 29/42 sizes.
