Description
Büchner funnel with standard ground joint 19/26 and filter plate, porosity 3, 200 ml is a laboratory vacuum filtration funnel made from high-quality borosilicate glass LBG 3.3. Each unit incorporates a sintered filter plate; porosity 3 corresponds to a pore-size range of 15–40 µm. It is intended for use in combination with suction flasks of article series FFK3. This GLASSCO-type funnel from manufacturer Labbox supports solid–liquid separations under reduced pressure in analytical and preparative work. The 200 ml capacity suits typical medium-scale batch filtrations, while the Normschliff 19/26 joint gives a standardized, secure connection to matching receivers. Borosilicate glass LBG 3.3 provides the chemical durability and thermal stability expected in everyday filtration glassware. Within the available porosity scale, grade 3 sits between coarser plates (porosity 1: 90–150 µm; porosity 2: 40–90 µm) and finer porosity 4 (5–15 µm), making it suitable for many precipitate collections. The integrated filter plate means separate discs are not required for this porosity class. Supplied as one piece for direct laboratory use.
This article is part of Büchner & filter funnels, in Funnels.

Questions about Büchner funnel with sintered disc porosity 3, cap. 200 ml , Ø 65 mm, cone 19/26
What is this article?
Büchner funnel with sintered disc porosity 3, cap. 200 ml , Ø 65 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.
