Borosilicate Glass Crystallizing Dishes

It is a cylindrical flat dish with a mouth and flat bottom parallel and perpendicular to the side with a large and deep surface,made of borosilicate glass 3.3.Large surface, mainly expanding heating surface and evaporating surface, deep dish, it is easy to hold more mother liquor; flat bottom, it is easy to monitor crystallization, with spout, it is easy to pour out solution in dish. The crystallizing dish is washed and dried, and the mother liquor which needs to be refined is put into the crystallizing dish for crystallization. In organic chemical reactions, there has never been a single reaction, in addition to the formation of major substances, there are other by-products and impurities. Therefore, in organic chemistry experiments, to obtain more pure substances, we must pay attention to refining work. The most common refining method is crystallization. Pure single crystals can be obtained by dissolving and crystallizing the substances to be purified with suitable solvents to remove impurities. The purpose of crystallizing dishes is to make crystallization experiments in laboratory or recrystallize liquids in order to achieve the purpose of refining and purifying. Large size crystal dishes are small batches of production tools
