FILTERING FUNNEL Meaning and
Definition
-
A filtering funnel is a laboratory apparatus used to separate solid particles from a liquid solution. It consists of a conical-shaped glass or plastic funnel attached to a long stem, which is typically made of glass. The stem connects to a flask or receptacle to collect the filtered liquid.
The main purpose of a filtering funnel is to perform a process called filtration. During filtration, the liquid mixture is poured into the funnel, allowing it to pass through a filter medium, such as filter paper or a porous ceramic disc, that is placed inside the funnel. The filter medium traps the solid particles or impurities present in the liquid, effectively separating them.
The conical shape of the funnel and the stem aid in directing the flow of the liquid, ensuring that it passes uniformly through the filter medium. This helps to enhance the efficiency of the filtration process, ensuring a clear and particle-free filtrate. Additionally, the stem of the funnel allows for controlled pouring of the liquid into the funnel, preventing spillage or splashing.
Filtering funnels are widely used in various scientific and analytical applications, including chemistry, biology, and environmental science. They enable researchers to purify and separate mixtures, isolate desired compounds, remove contaminants, or simply obtain a clear liquid for further experimentation or analysis.

Etymology of FILTERING FUNNEL
The etymology of the word "filtering funnel" can be broken down as follows:
1. Filtering: The word "filter" originated in the late Middle English period, derived from the Old French word "filtre" and the Medieval Latin word "filtrum". These words referred to a piece of felt used for straining liquids. Over time, "filter" came to be used as a noun for the device or process of removing impurities from liquids or gases.
2. Funnel: The word "funnel" has a longer history, dating back to Old English where it was spelled as "funnel" or "fonel". It came from the Latin word "infundibulum", meaning a funnel or a cone-shaped utensil. The Latin term itself was a combination of "in" (into) and "fundere" (to pour).
