conical glass flask
A conical glass flask, also known as an Erlenmeyer flask, is an essential laboratory vessel characterized by its distinctive cone-shaped design. The flask features a wide flat bottom that gradually tapers upward to a narrow neck, creating a stable and versatile container for various laboratory applications. This unique shape allows for efficient mixing and swirling of contents while minimizing the risk of spillage. The flask is typically made from borosilicate glass, ensuring excellent chemical resistance and thermal stability. Available in various sizes ranging from 25mL to 2000mL, these flasks are graduated with volume markings for precise measurements. The narrow neck can accommodate stoppers or caps for secure storage, while the wide base provides stability during heating or stirring operations. Modern conical flasks often incorporate advanced features such as uniform wall thickness for even heat distribution, reinforced rims to prevent chipping, and chemical etching for permanent graduations. These vessels are indispensable in chemical analysis, microbiology, and general laboratory procedures, serving functions from simple mixing to complex chemical reactions and culture growth.
