It can likewise be swirled without fear of the components spilling. It is named after the German chemist Richard Erlenmeyer. The conical flask's counterpart is the beaker. However the main distinction is that conical flasks may be stoppered making use of rubber bungs, so as the materials of the flask may be mixed or transported safely.

Beaker • A manufacturer is a form of activities glassware which consists of a cylindrical cup v a notch ~ above the height to enable for the putting of liquids. A beaker deserve to be placed over a burning fire (such as a Bunsen burner) to it is in heated.
Test pipe • A test pipe (Sometimes culture tube) is a type of activities glassware, composed of a fingerlike length of glass tubing, open up at the top, occasionally with a rounded lip at the top, and a rounded 'U' shame bottom. • They space designed to permit easy heater of samples, to be organized in a flame, and often are made the expansion-resistant glasses, such as Pyrex. Tests tubes are frequently preferred over beakers once multiple small chemical or organic samples need to be tackled and/or stored.
Test pipe Rack used to store and also hold test tubes in one upright position.
Test tube Holder supplied to hold test tubes, particularly when boil or containing harmful chemicals.
