The spelling of the word "schlenk line" is derived from its German origin, where the "sch" sound is pronounced as "sh." In the International Phonetic Alphabet (IPA), "sch" is represented by the symbol /ʃ/. The "e" in "schlenk" is pronounced as a short vowel, symbolized by /ɛ/. The second syllable, "line," is pronounced with a long "i" sound, represented by /aɪ/. Thus, the IPA transcription of "schlenk line" is /ʃlɛŋk laɪn/. It is a term commonly used in chemistry for a glass tube used to transfer air-sensitive compounds.
A Schlenk line is a sophisticated piece of laboratory apparatus commonly used in organic and inorganic chemistry to facilitate the handling of air-sensitive or moisture-sensitive reagents. It is named after its inventor Wilhelm Schlenk, a German chemist.
The Schlenk line consists of a glass or stainless-steel manifold, equipped with several valves and vacuum/gas lines, which allows for the manipulation of chemicals under an inert atmosphere. Its primary purpose is to maintain a controlled level of vacuum or an inert gas atmosphere during various chemical reactions or manipulations.
Typically, the Schlenk line is connected to a vacuum pump that maintains a constant negative pressure within the system. This negative pressure, along with the addition of inert gases such as nitrogen or argon, allows chemists to work with air-sensitive substances without exposing them to atmospheric oxygen and moisture.
The transfer of reagents or solvents between different glassware (such as flasks, tubes, or reaction vessels) is achieved through the use of specialized glass valves, sealed joints, and flexible rubber septa. These components can be adjusted to isolate specific portions of the Schlenk line, ensuring the controlled flow of gases and liquids.
Overall, the Schlenk line plays a crucial role in laboratory research, enabling chemists to manipulate and synthesize air-sensitive compounds without compromising their quality or reactivity.
The word "Schlenk line" is named after its creator, Wilhelm Schlenk. Wilhelm Schlenk was a German chemist who lived from 1879 to 1943. He is best known for his contributions to the field of inorganic and organometallic chemistry. The "Schlenk line" is a specialized piece of equipment used in chemistry laboratories, primarily for handling air-sensitive compounds and reactions. It consists of a glass manifold connected to a vacuum or inert gas line, which allows for the transfer of materials under controlled atmospheres. The term "Schlenk line" was coined to honor Wilhelm Schlenk for his pioneering work in the field.
