Tissue culture grade water is high-grade water with no impurities or contaminants. To be considered tissue culture grade, water is tested for the ability to support cell growth and maintenance in the laboratory when used to reconstitute cell growth medium. The pH of tissue-culture grade water should be between 5.7 and 7.0. Inorganic minerals, essential for cell growth, must be presenting minute quantities. Organic matter is absent, including natural and man-made organic molecules such as proteins, pesticides, herbicides, tannins and detergents. Microorganisms such as bacteria, viruses and algae are absent, as are organic breakdown products. The water is endotoxin free.
Bio-Logic Aqua Absolute Premium Standard™ tissue culture grade water (Trade Secret) meets or surpasses the above criteria and has a natural pH of 6.4. Due to a rare combination of purity, a slightly acidic pH, and an ideal mineral nutrient content, Bio-Logic Aqua is quickly and beneficially absorbed by damaged tissue.
