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

Procedure
Mix sodium chlorite (NaClO2) and hydrochloric acid (HCl) in a 1:1 ratio in a container. The dropper insert from our 100 ml bottles is suitable for this. Alternatively, you can use a Pasteur pipette (rinse well after using each chemical).
After only approx. 45 seconds you can already use the CDS created.
what is CDS ?

Finished Mychem CDS compared to the CDS you have prepared yourself
One drop of NaClO2 and HCI each corresponds to the effective quantity of eight drops of our finished CDS.
Example: 3 drops of NaClO2 mixed with 3 drops of HCl = 24 drops of Mychem CDS

Purity
The CDS obtained by mixing NaClO2 and HCl contains by-products from the raw chemicals and does not achieve the purity of our finished CDS.

The manufacturing process of our CDS is a special, elaborate Mychem in-house development based on the reaction process.
For the manufacturing process, we only use high-purity, very expensive raw materials that are not commercially available.
The result is our CDS purest Form.

The minimum shelf life is printed on the bottom of the bottle. This also applies after repeated opening.

The product can be stored away from sunlight at room temperature (refrigerator unnecessary).
