UPDI(ULTRAPURE DEIONIZED WATER) Chemical compatibility with O-rings, rubbers, & plastics

Ultra Pure Deionized Water (UPDI) is water that has had almost all of its mineral ions removed, such as cations like sodium, calcium, iron, and copper, and anions such as chloride and sulfate. It is used in various industrial and laboratory applications where high purity water is required, such as in the pharmaceutical industry, electronics manufacturing, and scientific research. Ultra Pure Deionized Water is essential for processes that require the elimination of impurities and contaminants. Proper handling and storage are crucial to prevent recontamination.
