A set of 9 conical funnels with different diameters for different sizes of laboratory apparatus. The cone of the conical filter connector is very flexible, with a smooth and wear-resistant surface.
Adapters of different sizes: Can be used alone or nested with one or more neighboring dimensions.
Made of vulcanized rubber with good elasticity, smooth surface and durability.
Filter adapter taper sleeves can be used alone or nested with adjacent sizes, reducing the risk of inserting and removing the glass stem through these rubber plugs.
Autoclavable: Fully functional even when not tightly fitted around the funnel rod used. They are also excellent for drilling special sized holes in rubber plugs or using more unstable rubber filter aids.
