This clever adapter has a coarse frit sealed between the #15 O-ring joint and the standard taper inner joint. The frit permits filtration of large particles before introduction into the flask and also serves as a bump trap for reactions being performed on a manifold. This product is available in 2 sizes. Each adapter is supplied complete with one CG-305-116 #116 Viton™ O-ring. The #15 joint uses a CG-150-06 clamp (not included).
