The difference between purified water and injection water

Injection water refers to water that meets the requirements of the Chinese Pharmacopoeia injection water.
water used for injection is distilled water or deionized water distilled water, and therefore weighed distilled water.
In order to effectively control microbial contamination and at the same time control the level of bacterial endotoxins, the design and manufacture of purified water and injection water systems have two major features: first, the increasing use of disinfection/sterilization facilities in the system;
water used to prepare the injection water, requiring one distillation or deionized water, i.e. purified water.
injection water is different from the general distilled water, deionized water and reverse osmosis method of preparation of medicinal purified water, mainly should be in the heat-free.
can dissolve powder needles or dilute injections by sterilized water from water injection.
difference between purified water and injection water is also in the water production process, purified water preparation process can have a variety of options, but the national pharmacopeia on the preparation process of injection water are limited conditions.
as the United States Pharmacopoeia clearly stipulates that the preparation process for injection water can only be distillation and reverse osmosis, the Chinese Pharmacopeia stipulates that the production process for injection water must be distillation.
these are necessary conditions for countries to ensure the quality of water used for injection, in accordance with their own realities.
the principle of selecting methods for the preparation of pharmaceutical water, in addition to controlling chemical indicators and particulate pollution, it is necessary to effectively deal with and control the contamination of microorganisms and bacterial endotoxins.
purified water system can be reverse osmosis, while injection water system is more use of distillation method, distillation water machine is often the purified water system distribution cycle circuit (water circuit) in the main water point.
domestic injection water are distillation method, which is related to the quality status of domestic reverse osmosis.
different distillation water machine on the source water requirements are different, different models of distilled water machine, due to performance differences, they can be purified water, deionized water, deep soft water as the source water, preparation to meet the standards of injection water.
On the other hand, water that meets drinking water standards as the source of water to prepare purified water, or purified water that meets the standards to prepare water for injection, does not necessarily guarantee that the water will meet the required standards, which is related to the performance of the equipment selected.
water quality of the source water must be monitored, and the water point should avoid the source of pollution as far as possible.
Injection water equipment is the result of distillation of purified water, and its bacterial endotoxins and other indicators are in line with the Provisions of China Pharmacopeia Injection Water, injection water equipment system mainly includes injection water preparation, recycling storage, dynamic distribution and process control and other major modules.
net Tray injection water equipment system using today's two-stage reverse osmosis purified water and fully automatic multi-effect distillation injection water treatment technology, the system adopts a fully automatic control mode, user-friendly design, safe, reliable, quality assurance.
application industry: can be used in medical devices, biomedicine, veterinary drugs, powder needles, in-body diagnostic reagents, clinical analysis and testing equipment, large infusions, medical sterile water and other industries water.
