1. Measure out 180 liters of double distilled or purified tissue culture water at ambient temperature
   in a stirred tank. While stirring, add the solutions without heating the water and ensure full recovery of the material from the bottles by rinsing them well.
    
2. Add solutions no. 1 and no. 2, then exactly 450 g sodium hydrogen carbonate and wait until complete dissolution.
   The recommended L-glutamine concentration is 4mM (116.8 g for 200 liters medium).
   Note that higher glutamine levels may lead to excess cytotoxic catabolite formation.
