Description
Büchner funnel with standard ground joint 19/26 and filter plate, porosity 4, 35 ml is a compact laboratory vacuum filtration funnel manufactured from high-quality borosilicate glass LBG 3.3. Each unit includes a sintered filter plate of porosity 4, giving a pore size range of 5–15 µm for fine particle retention during solid–liquid separations. The funnel is designed for use together with suction flasks of the FFK3 series, enabling efficient vacuum filtration on a small working scale. A standard ground joint NS 19/26 ensures a reliable seal to compatible receiving flasks, while the 35 ml capacity is ideal for micro- and small-scale preparative or analytical work. This GLASSCO-type Büchner funnel from manufacturer Labbox is supplied as one piece and supports routine filtration of fine precipitates and suspensions in research, quality-control and teaching laboratories. Borosilicate LBG 3.3 glass provides the chemical resistance and handling robustness required for everyday bench use. Net weight is 0,085 kg. The product family offers porosities of 90–150 µm (1), 40–90 µm (2), 15–40 µm (3) and 5–15 µm (4); this model is the fine porosity 4 variant.

Questions about Büchner funnel with sintered disc porosity 4, cap. 35 ml , Ø 30 mm, cone 19/26
What is this article?
Büchner funnel with sintered disc porosity 4, cap. 35 ml , Ø 30 mm, cone 19/26 is the article on this page. Luminix Health distributes Labbox 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.
