Place the needle on the cannula, pull off the needle protection slightly and bend the needle at the very base to an approximately 60 degree angle.
Now open the cannula (pull the plunger out of the cannula), place it on the table and add 1 drop of sodium chlorite far into the inside of the horizontal cannula. Then add 1 drop of hydrochloric acid a little less far into the horizontal cannula so that the two different drops do not come into contact.
Now put the plunger back in and place the cannula with the (bent needle) attached so that the needle is at the top and the drops in the cannula mix at the bottom of the plunger.
Immediately place the needle in the water glass (100ml) and activate the stopwatch!
After the first 60 seconds of yellow chlorine dioxide gas evolution in the syringe, press the syringe plunger to transfer the gas into the water.
Stir at the same time with the plastic spoon to ensure optimal mixing! Make sure that none of the mixture of the two drops is transferred into the water glass!
The approximate ppm value is now 008! If you open the flask again after emptying it for the first time and wait another 60 seconds for chlorine dioxide gas to develop and then empty it into the glass again while stirring at the same time, you will now have an approximate ppm value of approx. 012!
By adding 1 drop of DMSO, the remaining chlorine components are neutralized!
By adding 1 drop of lactic acid, the CDL that has just been produced is stabilized and therefore does not lose its effect!
Result of producing one drop of gas evolution in 100ml of double distilled water:
