Same thermal characteristics and mechanical strength as with standard borosilicate glass Erlenmeyer flasks; however, gently flared rim is not as heavily tooled. Economically priced. Ideal for student use and your budget!
The Origin of the Erlenmeyer Flask
The Erlenmeyer flask, also known as the conical flask, was named after the German chemist Emil Erlenmeyer. Emil Erlenmeyer, born on March 28, 1825, in Wehen, Germany, made significant contributions to the field of organic chemistry during the 19th century. His most enduring legacy, however, would be the flask that bears his name.
Emil Erlenmeyer is renowned for his work on various chemical reactions and his development of the Erlenmeyer flask in the 1860s. He designed this flask as an improvement over traditional flat-bottomed flasks. The key innovation of the Erlenmeyer flask was its conical shape, which allowed for more efficient mixing and swirling of liquids, as well as reduced risk of spills and splashes during reactions.
The Erlenmeyer flask's design is characterized by a flat bottom, a conical body, and a narrow, cylindrical neck. These features have practical advantages. The flat base ensures stability on flat surfaces, while the conical body allows for easy swirling and mixing of reagents without the risk of spillage. The narrow neck minimizes evaporation and limits the escape of hazardous fumes.
Evolution of the Erlenmeyer Flask
Over the years, the Erlenmeyer flask has undergone several modifications and improvements, adapting to the changing needs of scientists and the emergence of new materials and technologies. Originally, Erlenmeyer flasks were made from glass, which was the primary material for laboratory glassware. However, with advancements in material science, they are now available in various materials, including plastic and borosilicate glass. These variations provide options for different applications and preferences.
Graduated Erlenmeyer Flasks
To enhance the precision of measurements and reduce the need for additional glassware, graduated Erlenmeyer flasks were introduced. These flasks have volume markings etched onto the glass, allowing scientists to measure and mix reagents more accurately.
Chemically Resistant Coatings
For applications involving aggressive chemicals, specialized Erlenmeyer flasks with chemically resistant coatings have been developed. These coatings, such as Teflon or PFA (perfluoroalkoxy), protect the flask from corrosive substances and extend its lifespan.
The Erlenmeyer flask's versatility is one of its most compelling features, making it a valuable tool in laboratories across virtually all scientific disciplines.
