A Fleaker is a brand of container for liquids used in the laboratory. It can be described as a cross between the Griffin beaker and the Erlenmeyer flask. [1]Like a beaker, the bottom is flat, with the sides meeting the bottom at a 90-degree angle.
[2] Erlenmeyer flasks have wide bases and narrow necks. [3] They may be graduated, and often have spots of ground glass or enamel where they can be labeled with a pencil. It differs from the beaker in its tapered body and narrow neck. [4] Depending on the application, they may be constructed from glass or plastic, [5] in a wide range of volumes ...
