How Do You Spell WOULFE'S BOTTLE?

Pronunciation: [wˈa͡ʊlfs bˈɒtə͡l] (IPA)

The spelling of "Woulfe's bottle" can be tricky due to the unusual pronunciation of the surname "Woulfe." The IPA transcription of the name is /wʊlf/. The word "bottle," on the other hand, is more straightforward with an IPA transcription of /ˈbɑtəl/. When combined, the pronunciation is /wʊlf's ˈbɑtəl/. This term refers to a laboratory apparatus used for distillation or fractionation of liquids. It was invented by the Irish chemist Peter Woulfe in the 18th century.

WOULFE'S BOTTLE Meaning and Definition

  1. Woulfe's bottle is a glass vessel with a specific shape and function that is commonly used in chemistry laboratories. It is named after the Irish chemist Peter Woulfe, who is credited with its invention.

    The bottle has a distinctive design characterized by a pear-shaped body with a long neck and a side-arm tube, often bent at a 90-degree angle. It is typically made of glass to allow for transparency, facilitating observation of the contents.

    Woulfe's bottle is primarily used in laboratory setups that involve distillation, reflux, or fractional distillation processes. It is employed as part of the apparatus to separate and purify liquid mixtures or to capture gas produced during reactions. The side-arm tube serves as a vent to allow gases or vapors to escape while preventing the loss of valuable liquid substances.

    The functionality of Woulfe's bottle relies on the principle that when heat is applied to a mixture, the lighter components vaporize first, rising into the neck of the bottle where they condense. The condensate then flows back into the flask or vessel, promoting further separation and purification.

    Due to its versatile applications and effectiveness in several experimental procedures, Woulfe's bottle is considered an essential piece of equipment in many chemical laboratories. Its design allows for efficient and controlled distillation processes, making it a valued tool in the field of chemistry.

  2. A bottle with two or three necks, used in a series, connected with tubes, for working with gases (washing, drying, absorbing, etc.).

Etymology of WOULFE'S BOTTLE

The term "Woulfe's bottle" is derived from the name of an Irish chemist named Peter Woulfe who invented the apparatus. Peter Woulfe was born in 1727 in Ireland and was known for his contributions to the field of chemistry, particularly in developing laboratory equipment.

The "Woulfe's bottle" refers to a glass vessel used in chemical laboratories for various purposes, including the purification and collection of gases, distillation, and the separation of liquids. It consists of a pear-shaped glass container with multiple necks and side tubes. This design allows for the controlled flow of gases or liquids while minimizing the risk of contamination.

Although the exact date of its invention is uncertain, Woulfe's bottle gained popularity in the late 18th century and became a commonly used apparatus in chemistry laboratories.
