Pharmaceutical Purified Water Systems In Scientific Research Academy

  • Grade III water is low grade laboratory pure water, recommended for washing glassware; water for water bath, autoclave and ultrapure water system.

  • Grade II water is generally used for routine laboratory applications, such as the preparation of buffer solution, pH solution and microbial culture medium; Water supply for ultrapure water system, clinical biochemical analyzer, incubator and aging machine; Reagents can also be prepared for chemical analysis or synthesis.

  • Grade I water is often used for strict experimental applications, such as HPLC mobile phase preparation; GC blank preparation and sample dilution, HPLC, AA, ICP-MS and other high-precision analytical techniques; Preparation of buffer solution, mammalian culture medium and test tube baby; Preparation of molecular biological reagents (DNA sequencing, PCR amplification, etc.); Preparation of electrophoretic and hybridization experimental solutions, etc.


Case Study Of Pharmaceutical Water Systems In Scientific Research Academy

  • purified water distribution system

    Buffer And Media Preparation

    The grade of pure water required for reagent make-up or dilution will depend on the sensitivity of the intended application. For many general pharmaceutical applications where sensitivity is not the primary factor, purified water is sufficiently pure. It has the added advantage of not only having high purity in ionic terms, but also incorporating UV and filtration, can also ensure low levels of organic contaminants and microorganisms.

  • wfi distribution system

    Qualitative Analysis

    The water required for most qualitative analysis methods for major or minor constituents is general grade purified water with resistivity.

  • wfi storage and distribution system

    Microbiological Analysis

    Routine microbiological analysis requires purified water.

    This will be largely free of bacterial contamination and have low levels of ionic, organic and particulate impurities.

    Typical values are a resistivity of <1μS/cm,TOC<50 ppb and <100 CFU/ml bacteria count


  • purified water skid

    Water Analysis

    Water analyses are carried out for many different reasons. Requirements include ensuring potable water meets current standards, checking purification processes have been successfully carried out and environmental testing of feed sources such as lakes and rivers. Water analysis requires purified water for the preparation of samples, standards and blanks. This water must be of a known purity that is suffiaciently high so as not to interfere with the analytical techniques. Water analysis applications are usually performed with water with resistivity of <0.2μS/cm, TOC<50 ppb and a bacterial count below 1 CFU/ml.
