These versatile adapters provide a functional alternative to boring holes through traditional rubber stoppers. They are designed to fit Buchner and fritted glass funnels, porcelain filters without headpieces, and for reverse flow cleaning of filter crucibles. Adapters can be used to support funnels, Gooch crucibles, filter tubes, and other apparatuses in filtration assemblies, and are functional even if not tightly fitted around the funnel stem. They can be used individually, or nested with adjacent sizes.
