HIRSCH FUNNEL Meaning and Definition

  1. A Hirsch funnel is a type of filtration apparatus used in laboratories to separate solids from liquids and collect the filtrate. It consists of a conical-shaped funnel made of glass or porcelain with a perforated plate or fritted disc at the base.

    The Hirsch funnel is typically used in combination with a Büchner flask and a vacuum pump. The solid-liquid mixture is poured into the funnel, and a vacuum is applied to the Büchner flask. The vacuum creates a pressure difference, which allows the liquid portion of the mixture to flow through the perforations in the filter plate, while retaining the solid particles in the funnel.

    The perforated plate of the Hirsch funnel may have various pore sizes depending on the desired level of filtration and the size of particles to be collected. It is commonly used to separate fine precipitates or crystal solids from a liquid solvent or solution. The collected solid particles can then be further processed or analyzed as required.

    The Hirsch funnel is named after the German chemist and pharmaceutical entrepreneur Carl Friedrich Hirsch, who was known for his work in the late 19th and early 20th centuries. It is a versatile tool widely used in chemical research, pharmaceutical laboratories, and academic settings for various filtration processes.

Etymology of HIRSCH FUNNEL

The word "hirsch funnel" is derived from the name of the German chemist and physiologist, August Wilhelm von Hofmann. However, there seems to be some confusion regarding the exact origin of the term. It is commonly believed to be named after a German chemist named Emil Hirsch, who supposedly invented or popularized the use of the funnel for filtration. However, there is limited information or evidence regarding the existence of Emil Hirsch, and it is possible that he may have been confused with August Wilhelm von Hofmann, who made significant contributions to organic chemistry and taught at the University of Berlin. Therefore, "hirsch funnel" is likely a misnomer, and it should be attributed to August Wilhelm von Hofmann instead.
