18O water (H218O) is a colorless liquid at room temperature. The density of Water O18 is 1.11 g/cm3 at 20 ° C  and it boils at 100 ° C.


18O water, or 18O labelled water, is prepared by reducing copper (I) oxide with hydrogen:

Cu218O + H2  → Cu + H218O

18-O water (H218O) is used in different fields of chemistry. The most known applications are the following:

  • O18 Water is widely used in medical applications;
  • Oxygen-18 is used to create tailored organochemical compounds labelled with the radio isotope F-18 which is used for Positron Emission Tomography (PET), the latest cancer diagnostic technique;
  • Commonly used in organic synthesis as the source of 18O isotope;

At present, CPI Georgia can produce isotopically labelled water such as 18O-water (O18-water, water 18O, 18O-H2O) product with isotopic richness above 99% 18O. Other than 99% enrichment, isotopeshop.com offers different kind of Watre-O18 enrichment such as 98%, 70%, 20%, 98% for PET.
