About Ultrapure Water System

  • How long can the pure water and ultrapure water produced by ultrapure water machine be preserved?

    Generally speaking, the higher purity of water in the laboratory, the less likely it is to be stored for too long, with 18.2m Ω For CM ultrapure water, the longer it is placed, the more serious the decline is. Generally, the resistivity of ultrapure water placed for 1 hour will drop to 4m Ω Cm, pH will drop to about 5.7. At the same time, due to the influence of the environment, microorganisms in the water will breed rapidly.
  • What is the working principle of the ultrapure water system in the laboratory?

    The working principle of the ultra pure water system in the laboratory is that the tap water is pretreated through the precision filter element and activated carbon filter element to filter the particles such as sediment and adsorb peculiar smell, and then the water quality is purified and desalted through the reverse osmosis device. Its water quality can meet the national grade III water standard, and the wastewater produced by the reverse osmosis device is discharged at the same time. The reverse osmosis pure water is deeply desalted through the purification column to obtain primary water or ultrapure water.
  • How many grades of water is used in the laboratory?

    Ⅰgrade water is used for analytical experiments with strict requirements, including experiments with requirements for particles, such as water for high performance liquid chromatography.
    Ⅱ grade water is used for inorganic trace analysis and other experiments, such as atomic absorption spectrometry water.
    Ⅲ grade water is used for general chemical analysis experiments.
  • What industries are ultrapure water machines suitable for?

    Applicable to many industries, such as laboratory、electronic industrypharmaceutical industrypaint industrychemical industry and so on.
