Stem is 8mm O.D.×150mm length. XC-extra coarse, C-coarse, M-medium porosity.

For use with multi-neck flasks.

Design of funnel permits addition of solvents to flash chromatography columns without disturbing the silica-gel/packing layer. Lower end of the funnel is closed and the stem has a series of small holes through which the solvent drains....

C-coarse, M-medium porosity. (For porosity grade see table in appendix).

Funnels have 60° side angle and a standard taper inner joint.
