Description
Gas filter funnel, conical, 10 ml, porosity 2, NSK 14/23 is a specialised laboratory funnel fabricated from borosilicate glass 3.3 for gas filtration and related analytical procedures. The conical body holds a working volume of 10 ml and incorporates a fused VitraPOR® filter plate of 15 mm diameter with porosity 2. A standard ground joint NSK 14/23 allows secure connection to compatible glassware assemblies. This configuration supports controlled filtration steps where a defined pore size and reliable glass-to-glass joint are required. The item is offered in a pack of two pieces from manufacturer ROBU - Stereon. Borosilicate 3.3 provides the thermal and chemical stability expected in laboratory filtration glassware, while the permanently fused VitraPOR® plate ensures a stable filter medium within the conical funnel. Users can integrate the NSK 14/23 joint into existing apparatus for gas washing, particle retention or sample preparation workflows that benefit from porosity grade 2. The compact 10 ml capacity suits small-scale operations and precise handling of limited sample volumes under standard laboratory conditions.

Filter Funnel, conical, 10 ml, Por. 2, ST 14/23 cone is the article on this page. Luminix Health distributes ROBU - Stereon for laboratory use. It sits in Büchner & filter funnels, inside Funnels, in Labware.
A Büchner funnel is a perforated porcelain or plastic plate used with a rubber cone and vacuum to pull liquid through a filter paper. A filter funnel is the glass cone that holds a folded paper under gravity. The plate diameter decides the paper size.
A funnel guides a liquid or a powder into a narrower mouth. A filter funnel holds a paper. A Büchner funnel is the flat perforated plate used with vacuum. A separating funnel has a stopcock so two liquid layers can be run off one at a time. A dropping funnel adds a reagent slowly into a reaction. The bore and the stopcock are the parts that matter. This glassware is listed under ISO laboratory glassware.
