Description
Büchner funnel smoother 70 x 154 mm with a plate height of 14 mm is a sturdy laboratory accessory made of borosilicate glass 3.3. This larger-format tool is employed with nutsche filters and Büchner funnels to level and compact filter cakes during vacuum filtration, supporting homogeneous cake formation and improved washing performance in preparative and process-chemistry environments. Measuring 70 x 154 mm, it accommodates bigger funnel diameters typically used for higher-volume filtrations in research and pilot-scale laboratories. The Boro 3.3 construction delivers chemical durability against a wide range of solvents and reagents while remaining thermally stable under normal laboratory conditions. Delivered as a single unit with a net weight of 0,21 kg, the smoother is straightforward to handle and store alongside other glass filtration equipment. Offered by manufacturer Witeg, it contributes to reproducible solid-liquid separations by minimising irregularities in the filter bed. Applicable in synthetic chemistry, purification workflows and quality-control filtration where consistent cake geometry is advantageous.
This article belongs on Büchner & filter funnels, in Funnels.

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.
