Description
Gas filter funnel, conical, 10 ml, Por. 4, NSK 14/23 is a precision laboratory funnel engineered for gas filtration duties. Fabricated from borosilicate 3.3 glass, it features a fused VitraPOR® filter plate 15 mm in diameter with porosity grade 4 for finer particle retention. The conical profile and standard ground joint NSK 14/23 allow easy integration into jointed glassware assemblies common in organic chemistry, analytical laboratories and gas purification setups. Supplied by manufacturer ROBU - Stereon in packs of 2 pieces, the item is practical for laboratories that maintain multiple filtration stations. Borosilicate 3.3 delivers excellent thermal and chemical durability for everyday use under varied conditions. With a 10 ml capacity the funnel is ideal for small-volume gas streams, sample preparation and protective filtration. Porosity 4 provides a finer pore structure than coarser grades, supporting applications that demand tighter particulate control. The seamless filter-plate fusion and reliable NSK joint contribute to consistent, reproducible results in filtration and purification protocols.

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.
