O
O it is a mouth, the bottom and side vertical, parallel, large and deep cylindrical, flat-bottomed pan with spout. Large, mainly is the expansion of heating surface and water surface evaporation; dish deep, is convenient for more liquor; flat, convenient monitoring crystal fold out; with mouth, convenient dish of solution in the dump.

O in organic chemistry, never a single reaction, the reaction in addition to the main substances, there are other side products and impurities. Therefore in the organic chemistry experiment, to achieve a pure substance must focus on refining. The most common, the most commonly used method is the crystallization purification. With a suitable solvent, so that to be purified by dissolving, crystalline material, to remove impurities, are pure single crystal. Crystallizing dish uses, is devoted to the laboratory for crystallization trials, or liquid crystallization, refining, in order to achieve the purpose of purification
