2) purified water: it shall meet the standard of purified water contained in Chinese pharmacopoeia 2010.


In the process of water production, the resistivity value of purified water is usually measured online to reflect the concentration of various ions in the water.

Purified water resistivity of the pharmaceutical industry should normally acuity 0.5 M Ω. CM / 25 ℃, for injection, eye drops container flush with the resistivity of purified water should be 1 M or more Ω. CM / 25 ℃.


3) water for injection: it shall conform to the water for injection standard contained in Chinese pharmacopoeia in 2005.


Blue sky pharmaceutical purified water equipment system adopts the current advanced RO and EDI purified water technology, the water quality meets the production water requirements of customers, in line with GMP, FDA and other certification requirements.

The system has the advantages of humanized design, modular installation, small occupation area, simple and convenient operation, stable operation, high efficiency and energy saving.
