Water for injection prepared by distillation

The pharmacopoeia standard for endotoxin in water for injection is not higher than 0.25EU/ml, and the level of endotoxin in drinking water is approximately 10-100EU/ml. After the drinking water is purified by the purification machine, Its endotoxin level is approximately 1-10EU/ml, which is equivalent to the traditional pretreatment +RO/EDI purification machine's endotoxin removal capacity of 1-2log. Distillation is divided into three kinds: single effect distillation, multi-effect distillation and hot pressure distillation. At present, single effect distilled water machine has been eliminated because of no energy saving and other reasons. Multi-effect distilled water machine and hot pressure distilled water machine are widely used in industrial pharmaceutical enterprises.、
