The Erlenmeyer flask is a type of laboratory glassware that was designed by German chemist Emil Erlenmeyer in the 1860s. The flask has a conical shape, with a flat bottom and a narrow cylindrical neck. The design of the Erlenmeyer flask allows for easy mixing and swirling of liquids without spilling, and the narrow neck makes it easy to pour liquids while minimizing the risk of splashing or spilling.
If you are looking to buy Erlenmeyer flasks, there are a variety of scientific supply companies that sell them online. These flasks are commonly used in chemistry labs and can be purchased in various sizes, ranging from small flasks for individual experiments to larger flasks for bulk mixing. When shopping for Erlenmeyer flasks, be sure to consider the size and material of the flask to ensure that it meets your needs.
