Büchner funnel smoother 35 x 118 mm with a plate height of 8 mm is a precision laboratory accessory fabricated from borosilicate glass 3.3. This robust glass tool is designed for use with nutsche filters and Büchner funnels, enabling even distribution and smoothing of filter cakes during vacuum filtration procedures in analytical and preparative chemistry workflows. The dimensions of 35 x 118 mm provide a practical working surface suited to smaller funnel sizes commonly found in research and quality-control laboratories. Manufactured from chemically resistant Boro 3.3 glass, the smoother withstands typical laboratory solvents and thermal variations encountered in routine filtration work. Supplied as a single piece with a net weight of 0,04 kg, the item integrates easily into existing glassware sets. The product originates from manufacturer Witeg and supports reproducible sample preparation by helping to achieve uniform cake surfaces that improve filtration efficiency and subsequent washing steps. Ideal for organic synthesis, pharmaceutical development and general wet-chemistry applications where controlled solid-liquid separation is required.
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.
