What should you pay attention to when buying colloidal silver?

Water quality:

Distilled water with strict specifications:

  • Conductivity: <10 µs/cm
  • pH value: 5.0 - 7.0
  • Evaporation residue: < 3.0 mg/l

It is also important that no additives are added during the manufacturing process to increase the conductivity of the distilled water.   

► Appearance:

Colloidal silver in its liquid form is usually colorless, slightly yellowish or clearly yellow to brown in color. Especially in higher concentrations, the silver water can take on an increasingly yellowish color.

Important: Yellowing or a lack of yellowing does not allow any conclusions to be drawn about the quality. The silver water must always be clear - without cloudiness or solid particles. 


Depending on what the colloidal silver is used for, different concentrations are suitable. As the ppm number increases, the concentration of colloidal silver also increases.

Since the ideal concentration varies depending on the application, we offer colloidal silver in different strengths .

Additional Information:

The colloidal silver 25 ppm is freshly made with highly pure distilled water under qualified laboratory conditions and delivered in a dark glass bottle. Production takes place in the pharmacy under monitored laboratory conditions. The colloidal silver is produced electrolytically using an appropriate generator. Tiny particles are formed from 99.99% pure silver and distributed in distilled water. We work without using any additives. Please note: Colloidal silver is not a medicine and therefore does not indicate an indication. For legal reasons, we only offer colloidal silver for technical purposes. Not for ingestion.

Effectiveness of silver

The effectiveness of silver can be attributed to the oligodynamic effect. This effect is described by the Swiss Carl Wilhelm von Nägeli. It states that the ions of some metals can have a damaging effect on various pathogens. In addition to bacteria and fungi, these pathogens also include viruses. The extent to which the effects of colloidal silver are comparable must be examined and proven in further studies.
