Conical flask 1000 ml Kn-3-1000-42 with graduation

A conical flask Kb-3-1000-42 is a widely used type of laboratory flask, which is characterized by a flat bottom, a conical body, and a cylindrical neck. The conical shape makes it easy to mix the contents during the experiment, either by hand or with a special laboratory shaker or magnetic stirrer. The narrow neck keeps the contents from spilling, and it also keeps the contents from evaporating better than a beaker. The flat bottom of the conical flask prevents it from tipping over.
