Description
The Büchner funnel 50 ml P1 is a glass filter funnel for vacuum-assisted solid-liquid separation in routine laboratory work. It incorporates a sintered filter plate of porosity grade P1 with a plate diameter of 35 mm and a stem outer diameter of 10 mm, giving a compact 50 ml working volume suited to small-batch filtrations of suspensions, precipitates and crystalline products. The integrated frit removes the need for loose filter paper in many protocols and supports repeated cleaning and reuse under standard laboratory conditions. Offered by manufacturer Witeg as a single-piece unit with a net weight of 0,044 kg, the funnel belongs to the established family of glass filter nutschen used across chemistry, biochemistry and materials laboratories. Its narrow stem connects readily to common vacuum filtration assemblies and receiving flasks, while the defined P1 porosity helps achieve consistent particle retention when clarifying solutions or collecting solids. The robust all-glass construction withstands typical solvent exposure and thermal handling associated with everyday filtration tasks, making the 50 ml P1 model a practical choice for analytical and preparative workflows that require reliable, paper-free filtration on a modest scale.

Questions about Filter funnels, 50 ml, P1 disc dia.: 35
What is this article?
Filter funnels, 50 ml, P1 disc dia.: 35 is the article on this page. Luminix Health distributes Witeg 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.
