Instructions for the preparation of chlorine dioxide solution


Make sure the room is well ventilated, as chlorine dioxide gas escapes during the chemical reaction and you must not inhale it.
Be careful to mix only small amounts, e.g. three drops each. Larger quantities produce large amounts of gas.


Drop a 1:1 ratio of sodium chlorite (NaClO2) and hydrochloric acid (HCl) into a clean, dry (non-metal) container. The dropper insert from our 100ml bottle is suitable for this. Alternatively use our Pasteur pipette (rinse well with water after use of each chemical).
After about 45 seconds you can add your desired amount of water and the resulting CDL is ready.

Ready-made Mychem CDS in comparison to home-made CDS

One drop of each NaClO2 and HCI corresponds to the effective amount of eight drops of our ready-made CDS.
Example: 3 drops of NaClO2 mixed with 3 drops of HCl = 24 drops of Mychem CDS.


The CDS obtained by mixing NaClO2 and HCl contains by-products from the raw chemicals and does not reach the purity of our finished CDS.
The manufacturing process of our CDS is a special, elaborate Mychem proprietary development based on the reaction process. For the manufacturing process, we use only high-purity, very expensive raw materials that are not commercially available. The result is our CDS in its purest form.
