CDS Made In An All-Glass, Gas-Tight Container In 3 Hours 

 
 
Test #2 for this 250ml flask. Same recipe as before. Measurements will be taken later. 

Polishing the bottle neck-to-stopper joint and applying water to the joint as it was being closed, has stopped all CLO2 gas leakage from the flask. Nothing smelled. 

And, as a reminder, this bottle is all glass including the "cap" (stopper). The glass-to-glass joint does not use any plastic seal, only water-wet glass. 

   
+3 hours. It is now in the fridge where it will cool down and activate a little more. Will take measurements later today. 

   
This method is called "Quick CDS-Dry" and there is also a "QCDS-Wet" method. 

SCF = Sodium Chlorite Flakes
CAC = Citric Acid Crystals

Citric acid does not gas into CDS, but 4% HCL does. That raises the TDS (total dissolved solids) creating a "dirty" CDS. 

SCF can be stored for at least 20 years, and CAC at least 12 years. 

Sodium chlorite solution begins to lose potency at about 18 months, and 4% HCL will last about 3 years.
