Erlenmeyer flask. An Erlenmeyer flask, also known as a conical flask (British English) [1] or a titration flask, is a type of laboratory flask with a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825–1909), who invented it in 1860. [2] Erlenmeyer flasks have wide bases and narrow ...
Büchner flask or Sidearm flask or Suction flask—they are a flat-bottomed flask, but made of very thick and resistant glass. They are usually a cone shape—similar to the shape of an Erlenmeyer flask, but also have side neck, usually affixed to the side, 2 / 3 up from the bottom.
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.
Three beakers, an Erlenmeyer flask, a graduated cylinder and a volumetric flask. Laboratory glassware is a variety of equipment used in scientific work, traditionally made of glass. Glass may be blown, bent, cut, molded, or formed into many sizes and shapes. It is commonly used in chemistry, biology, and analytical laboratories.
Cross section of a Büchner Flask. Note the hose barb pointing right for attaching a vacuum source.
