These neoprene rubber adapter sets consist of seven cones designed to fit Büchner and fritted glass funnels (such as item #'s CG-1888 and CG-1402, for example). They also can be used with Gooch crucibles, filter tubes, and other filtration needs. The adapter does not need to be fitted closely around the funnel stem to form a vacuum-tight seal, making it far easier and safer than trying to insert a filter stem into a bored hole rubber stopper. The individual cones can be used individually or nested to provide an optimal fit. These adapters are also autoclavable.
These are sold as a set of seven nesting cones in the sizes shown below. These are sold as a set only:
