Addition Funnel, Graduated w/ Dual PTFE Stopcocks

This cylindrical style addition funnel is graduated with a double scale of numbers, one up from the stopcock and one down from the capacity line. The standard taper top outer joint and standard taper lower inner joint are both the same size. A second PTFE stopcock is incorporated into the pressure equalizing arm to permit the funnel to be filled without exposing the system to the atmosphere. The 14/20 versions are supplied with a CG-3000 stopper. The overall height is identical to the corresponding CG-1700 model.  The stopcock bore on sizes 250 mL and below is 2 mm; it is 4 mm on the 500 and 1,000 mL and it is 6 mm on the 2,000 mL.  For a similar item without the sidearm stopcock see CG-1712.

Replacement plugs are item # CG-424-XX.
