Water is the most universal solvent and is also the most common component in natural cells and tissues.

LS 016-01 is the cell/tissue culture grade pure water prepared through reverse osmosis (RO) filtration, 2 steps of endotoxin removal filtration  and final ultra pure water system resulting in the water resistance of max. 18 MΩ. By these procedures, impurities are removed completely. Hence, the experimental errors due to lab water can be reduced and the high reproducibility can be provided. Cell/Tissue Culture Grade Pure Water may be used for dissolving powder media and reagents, and other various cell/tissue culture experiments.

Storage/Stability
Cell/Tissue Culture Grade Pure Water should be stored at 15~30°C. Deterioration of the solution may be recognized by (1) precipitate or particulate matter throughout the solution, (2) cloudy appearance, (3) color change, and/or (4) pH change. Product label bears expiration date.

Biological Performance Characteristics
The growth-promoting capacity of Cell/Tissue Culture Grade Pure Water is tested in a medium containing 10% FBS using an appropriate cell line(s). Growth rates are examined through three subculture generations and compared with parallel cultures grown in standardized control medium. Cells are counted and growth is plotted as a logarithmic function of time in culture, and seeding efficiency, doubling time, and the final cell density are determined. During the testing period cultures are examined microscopically for a typical morphology and evidence of cytotoxicity.
