Erlenmeyerflaska

The Erlenmeyerflasche, also known as the Erlenmeyer flask, is a common laboratory glassware device used primarily for mixing, heating, and storing chemical solutions. It was developed in 1860 by the German chemist Emil Erlenmeyer. The flask features a conical body with a flat bottom and a cylindrical neck, which allows for easy mixing by swirling without the risk of spillage.

Erlenmeyer flasks are typically made from borosilicate glass, known for its thermal resistance and chemical durability, making them suitable for heating and reactions involving varying temperatures. Some versions are made of plastic for lightweight and shatterproof applications, especially in educational settings.

The shape of the Erlenmeyer flask facilitates the containment of vapors and minimizes evaporation. Its narrow neck can be sealed with corks, stoppers, or specialized caps to prevent contamination or evaporation of volatile substances. The flask often includes graduated markings for approximate volume measurement, although it is not as precise as volumetric glassware.

This laboratory vessel is widely used in chemistry, biology, and medical laboratories. It supports tasks such as titrations, culturing microorganisms, and preparing chemical reactions. Its design allows for easy handling and pouring, reducing the risk of splashes or spills.

Overall, the Erlenmeyer flask is an essential tool for laboratory processes, valued for its versatility, durability, and ease of use. Its functional design has remained largely unchanged since its invention, illustrating its effectiveness in scientific applications.
