Tap water and rain water are not pure. They contain salts and dissolved gases. Water is often distilled to increase purity. Most of the salts are left behind but the water may still contain dissolved gases. The presence of carbon dioxide reduces the pH of the water considerably.
Collected water vapor that is free of impurities and most minerals. Distilled water is perfect for humidifying cigars, it has none of the additives present in most domestic water supplies, such as chlorine.
Water that has been purified via an evaporation-condensation cycle. After passing through the cycle, it contains small amounts of dissolved solids.
water that has been purified by distillation
water heated to the boiling point, vaporized, cooled, condensed, and collected so that no impurities are reintroduced.
Water which has been freed of ions by a process of vaporization and subsequent condensation.
water that has undergone the process of evaporation and condensation and has had the minerals removed.
Prepared by thermal distillation using a still of all-borosilicate glass, fused quartz, tin or titanium with the distillate meeting the following characteristics of Type I (Type II) water: Resistivity (megohm-cm @ 25øC) greater than 10 (greater than 1) Conductivity (umho/cm @ 25øC) less than 0.1 (equal to 1) Total oxidizable organic carbon (mg/L) less than 0.05 (less than 0.2) Total solids (mg/L) less than or equal to 0.1 (equal to 1) SiO2 (mg/L) less than 0.05 (less than 0.1)
Water that has had all of the chlorine, minerals and nutrients removed from it. Do not use for drinking water due to the lack of necessary trace elements. However, it is acceptable for misting the tank or use in a humidifier if you have exceptionally hard water. It will eliminate the mineral deposits on the side of your tank that sometimes form when using tap water.
Water that has been collected from a municipal or well/spring water supply, and distilled.
water that has been treated by boiling and condensation to remove solids, inorganics, and some organic chemicals.
Water which has been boiled and the steam from it condensed; it therefore contains no dissolved solids.
Water which has had salts removed by distillation. It is very pure, but does contain some dissolved gases.
pure water free of dissolved salts
Water formed by the condensation of steam or water vapor.
Water which has been purified by vaporizing the liquid and collecting the vapor which is then condensed back to a liquid having, in the process, removed the contaminants.
A high quality water purification by activated carbon filtration, deionization and sterilization to ensure the most natural compound that aids in preventing hypohydrus conditions.
Water that has been purified. It is often used to clean fragile items, as it has no mineral deposits that could damage the delicate fibers.
Water which has been cleansed by passing through one or more evaporation-condensation cycles until it contains a very low amount of dissolved solids (usually less than 5.0 ppm TDS).
Water that has been purified through a process of evaporation and condensation.
Distilled water is water that has virtually all of its impurities as well as electrolytes removed through distillation (boiling the water and re-condensing the steam into a clean container, leaving contaminants behind).
