Made of top-grade rubber 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 are highly versatile, and they allow connections to be made that otherwise wouldn’t fit.
- Can be used individually or nested with adjacent sizes
- Provide an excellent alternative to boring special size holes in rubber stoppers
