Set of seven neoprene adapter cones designed to fit Buchnew and fritter glass funnels, porcelain filters without headpieces and for reverse flow cleaning for filter crucibles.

• Neoprene
• Autoclavable

Adapters can be used to support funnels, Gooch crucibles, filter tubes, and other apparatus in filtration assemblies. These adapters are functional even if not tightly fitted around the funnel stem. They can be used individually or nested with adjacent sizes. Adapters provide an excellent alternative to boring special size holes in rubber stoppers. Autoclavable.
