Description
Micro filter funnels, 0,8 ml, P4 are compact glass filtration devices intended for microscale solid-liquid separations in the laboratory. Each unit combines a sintered filter plate of 10 mm diameter with a stem of 6 mm diameter, giving a working capacity of 0,8 ml that minimises sample hold-up. The defined P4 porosity supports controlled particle retention during gravity or vacuum filtration of small aliquots. These micro nutsche funnels from manufacturer Witeg fit the needs of analytical chemistry, organic work-up and quality-control workflows where only limited material is available. Supplied as a single piece with a net weight of 0,004 kg, the funnel is easy to handle inside fume hoods, glove boxes or crowded benches. The slender stem integrates readily with common receivers and adapters, while the small plate diameter keeps the overall footprint modest. Researchers use such glass frit apparatus for clarifying reaction mixtures, isolating micro-precipitates or preparing samples ahead of spectroscopic and chromatographic analysis. Robust construction allows repeated laboratory use under typical filtration conditions without requiring larger nutsche equipment.
This article is part of Büchner & filter funnels, in Funnels.

Questions about MICRO FILTER FUNNELS, 0.8 ML, P4 DISC D
What is this article?
MICRO FILTER FUNNELS, 0.8 ML, P4 DISC D 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.
