* If bidistilled water is used, the specified production time must be extended by 5 minutes.
Do not heat the silver solution during and after the process!
At low concentrations, colloidal silver is colourless and tasteless. At higher values, a discolouration may
occur. The higher the concentration, the more intense the metallic-bitter taste, regardless of the colour or
quality of the silver solution.
Recommended concentration for nearly all applications:
25 ppm or 50 ppm (even more effective).
Optimal production: drinking glass with 200 ml (250 ml)
Production time: 25 ppm = 15 min (19 min at 250 ml)
50 ppm = 30 min (38 min at 250 ml)
Colour of silver solution
Higher concentrations of silver can stain the water (yellow/brown).
This colour shows high purity of the water used, but is not a measure of the concentration. Even with the
same production time, each solution can discolour differently. At higher concentrations, a black coating
sometimes forms on the electrodes and on the bottom of the glass. At low concentrations or short production
time, these particles are also present in the same ratio, but hardly visible.
Milky white/gray discolouration is caused by contamination or the use of tap or mineral water. Do not drink!
Measurement of concentration
Please note: With conductivity meters (TDS meters) it is possible to determine real solutions such as saline
solutions, but not the concentration of metal dispersions, e.g. colloidal silver (even if the TDS meter is
calibrated in ppm). The values given in our table were determined and confirmed by means of complex
laboratory tests.
Storage of colloidal silver
The finished silver solution can be used for several months, but gradually diminishes in its effect. Colloidal
silver with a large amount of positively charged ions is particularly effective and should therefore be used
fresh.
In order to keep the silver solution in its optimum condition for a long period of time, the following must be
observed:
Do not store in plastic or metal containers, store in dark glass bottles.
Do not place in electromagnetic fields (next to electric stove, TV, stereo, etc.).
Do not refrigerate, store in a cool place.
Care and maintenance of the device
The generator is maintenance free. Clean with a damp cloth when the power supply is unplugged.
Occasionally remove deposits between the sockets.
Care and replacement of silver electrodes
Wipe the silver electrodes vigorously with kitchen paper or cloth after each operation. Do not use silver
cleaner or scourer! Always insert the electrodes with the same end. If the electrodes have reached the
diameter of a pencil lead and could break, it is time to replace them. A pair of silver electrodes is enough to
produce about 400 litres of 10 ppm or 150 litres of 25 ppm colloidal silver.
Beware of replacement silver electrodes!
Original electrodes are chamfered to a certain angle, to avoid damage to the sockets. Our former standard
size of 2.7 (2.5) x 82 mm has been copied several times by other manufacturers. Imitations are offered as
original or universal electrodes. These products rarely match the high degree of purity and can lead to a loss
of warranty if the sockets are damaged.
Accurate silver release with the best quality can only be achieved with original electrodes!
