Making up solutions to a known volume are a piece of cake with this Volumetric Flask! Analytical chemists and neighborhood mixologists agree; the Volumetric Flask is the must-have laboratory (or bar) tool. This Volumetric Flask is made of soda-lime glass and is mostly used for storing chemical solutions, (and in a stylish way I might add.) It should not be used for heating things up so there is no need to fire up that Bunsen burner. Pocket protector not included.
