Distillation is the technical process for chemical and microbiological purification of material water through steam-liquid phase transition method and separation method.
During this technical process, the water is evaporated and the steam produced isolated from the water. What’s more, the unevaporated water that flow back dissolved solid substance, non-volatile matter and high molecular weight impurities.
During the process of distillation, low molecular impurities may be taken along in the steam produced by water evaporation in the form of water spray or water drop. Under this circumstance, we need a separating unit to remove the thin water spray and the carried impurities, including endotoxin. The purified steam after condensation will become water for injection.
At least 99.99% endotoxin content may decrease through distillation method.
