Description
Filter funnel Ø 55 mm 25 ml P5 is a Hirsch-style glass filter funnel engineered for laboratory filtration of fine particulates. Featuring a 55 mm diameter, 25 ml capacity and a P5 porosity fritted plate with 25 mm outer diameter, it delivers controlled retention characteristics suited to analytical and preparative procedures. The funnel, from manufacturer Witeg, is fabricated from durable laboratory glass compatible with common solvents, aqueous solutions and dilute reagents. Its compact Hirsch design minimises dead volume, supporting efficient recovery of limited sample amounts during vacuum or gravity filtration. Ideal for use with Büchner flasks and standard filter assemblies, the unit assists in precipitate collection, solution clarification and sample preparation across research, teaching and quality-control environments. Offered as one piece with a net weight of 0,02 kg, this filter funnel provides a reliable, dimensionally consistent tool for everyday solid-liquid separation tasks that demand a finer porosity grade.
This article is part of Büchner & filter funnels, in Funnels.

Questions about Filter funnels (Hirsch funnel) 55 mm dia
What is this article?
Filter funnels (Hirsch funnel) 55 mm dia 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.
