Description
Gas filter funnel, conical, 20 ml, porosity 2, NSK 19/26 is a specialised laboratory glassware item for filtration tasks. Fabricated from borosilicate 3.3, the conical funnel incorporates a fused VitraPOR® filter plate of 20 mm diameter with porosity grade 2 together with a standard ground joint NSK 19/26. The 20 ml working volume suits small-scale gas and liquid filtration in analytical and preparative workflows. Its conical geometry promotes efficient flow and easy handling when connected to compatible glass assemblies. Laboratory users employ this funnel in analysis funnels, glass funnel setups and related filtration procedures that require a defined porous glass medium. The robust borosilicate construction delivers the chemical and thermal stability expected in routine laboratory environments. Offered as a pack of 2 pieces from manufacturer ROBU - Stereon, the funnel integrates readily into existing glassware systems for reproducible filtration results in research and quality-control settings.
