"Its just a matter of Voltage ...."

Our manufacturing process is unique to us. Our constant aim is to provide high quality at a reasonable price & because of this, we have a growing customer base that includes many Natural Therapy Centres, Holistic Practitioners and various other commercial clients as well as thousands of private clients.

We always endeavour to keep our process as efficient, cost effective and carbon friendly as possible. Our extensive quality checks are vital part of our process and explained below.

Over the years, we experimented with various designs, having looked at most of the available commercial products on the market. We don't use commercially available generators because through experimentation, we have found several serious flaws which could possibly be dangerous, especially in the wrong hands. See FAQ's for a detailed explanation but the usual integrated design does not allow for the "Maturation" part of the process, which takes a considerable amount of time to complete."Maturation" is a very important step, as up to 1 in 5 batches can fail to reach a stable equilibrium.

Our design utilises laboritory grade borosilicate glass reaction vessels with separate/removable electrode assembly, so we can mature one batch in its original vessel whilst making more in another.

The maturation step is unique to our process & is vital to produce a high quality solution.

Every batch we make is tested at our production facility. You cannot make high quality solutions and develop a good reputation without rigerous testing. We have to produce quality certificates for certain clients who use our product as an ingredient, so we collect production data and produce a certificate of manufacture where needed.

Thanks to the in house IT expertise, we run an IBM Lotus Notes environment that has collected data for years and goes back to 2005. Prior to that we kept paper records which are still around somewhere!

We make Isolated Colloidal Silver. Isolated means that the colloid contains silver ions (AG+) & very small silver particles (AG-) suspended in a medium (distilled water) with an electrical charge (Zeta Potential). You will see many methods of producing Colloidal Silver but ideally it would be made using an electrolytic process using pure silver with pure water.

Two problems:

Pure water doesn't conduct electricity.
Pure silver is never pure, it is 99.9% 99.99% or 99.999% pure. There will always be a trace of impurity. Sterling silver is only 90% pure and is not used.

Silver Chloride

To overcome problem 1 above, certain web authors suggest you make a saline solution and add this dropwise to the pure water. I find this quite worrying because a milky white substance (Silver Chloride) is also produced. Although they insist this isn't a problem the FDA (US Food & Drug Administration) have stated that this could lead to Argyria. See Research & FAQs for further information. There are other catalysts recommended such as sodium bicarbonate (Baking soda) all of which are unnecessary and should never be used.

We NEVER use additives.

We use fine silver (.999) for our electrodes & is certified .999 fine silver. There are purer silvers available but the cost increases accordingly. See FAQs but it has been shown that the purity of the water is more important than the purity of the silver. We find .999 perfect.

The picture shows two electrodes from an experimental test generator after a batch had been produced. The centre wire is an unused piece of silver, for comparison. Note the discolouration on the right hand electrode. The electrodes we use now are much larger but to get the whole electrode into the photograph makes it difficult to see the discolouration. We also use 6 electrodes per generator, which gives a much better and consistent field in the reaction vessel.

Steam distilled water is the best.


	Distilled water is extremely difficult to obtain these days because it is expensive to produce. Tap/filtered/softened water is totally unsuitable as it may still contain many heavy elements and could create harmful compounds during the electrolysis process. Mineral water is unsuitable because it contains minerals! We make our own steam distilled water using commercially available units. The final quality is excellent and it reads 0 PPM. Deionised water is around 4 PPM and our tap water is 275 PPM. Note 0 PPM means less than 1 PPM.

Devon water is possibly the softest water in the UK having been collected from Dartmoor. This famous moor is part of a an ancient batholith which is a volcanic magma chamber that has been eroded over time and is now exposed, producing the beautiful Tors and landscape. Because it is made up of igneous rock, rain water runs off and is collected without any significant mineral content being imparted. This means that we only have to distill our water ONCE to produce the desired quality necessary for production. The distillation process is the most energy hungry part of the process and we are deliberately here because of the water supply. I have noticed other manufacturers using a double or triple pass process - this is a total waste of energy and is ecologically unsound, emitting 2 - 3 time the carbon required to obtain the same product. In this day and age, this is very important and we are fully aware of our carbon commitment & please refer to our Ecology policy to see what we are doing about it.


Colloidal Silver is light/UV sensitive. If left unprotected it can oxidise and turn grey in colour. We use medical grade glass & plastic amber light proof bottles. We recommend you keep the bottle in a cool dark cupboard.

Our process starts by testing the steam distilled water with a calibrated PPM meter (Parts Per Million) to determine the impurities in the water. We call this the "Base count". We use a Hanna DST-1 PPM Meter.

Cleanliness is imperative in all stages of production. The reaction vessel & silver electrodes are thoroughly cleaned after each use. During the whole process, only glass is used as this is deemed inert. The only man made item used is the DST meter. We use glass reaction vessels, glass funnels and glass bottles. This helps to preserve the charges on the silver particles.

We then assemble the reaction vessels. We use laboritory grade borosilicate glass reaction vessels and six silver electrodes. Using constant current stabilised power supplies,(One per vessel) we pass a steady current through the electrodes. This is also done in the dark to preserve the delicate charges.

Using over 30 volts to start the process, the current will rise to its optimum level, then the voltage is automatically reduced to maintain the correct current. This is very important as the size of the particles is directly related to the current.

If the current isn't controlled, a "Runaway" reaction will occur and larger, ineffective, particles will be produced. We have found that the optimum current varies depending on many other variables.

Power supply and multimeter(Ammeter) for one of our generators.

The time taken for the reaction to complete is dependent on the temperature of the water but we estimate the time necessary from the initial temperature & the ambient lab temperature. We use an external heat source, when necessary, to maintain the reaction in the correct temperature range and the convection currents help to continually stir the solution in a natural manner, so no mechanical aids are required.

Although increased heat decreases the reaction time and particle size, it can also produce a larger range of particle sizes. We know from experimentation the range to use and it uses less energy, which has to be a good thing these days. The smaller the particles the better the quality of the Colloidal Silver. We can tell when the reaction is nearly complete by the voltage. We use an ammeter to monitor the exact current for each vessel.

We aim for a concentration of 12 - 14 PPM for safety reasons ( See FAQs and Argyria). We do not make concentrated batches and water it down. When the colloid is at the correct concentration, it has to pass our quality checks (Maturation) and only then bottled into an amber light proof bottle with a Klick-Loc cap.

- The most important step.

As stated in FAQ's, if the silver particles are too large, the Colloidal Silver is useless & will not work. This is why this stage of the process is so important.

Maturation is more than important. We can make Colloidal silver one day and repeat it the next day with different results. Although ambient temperature and final current are important, it also seems to be dependent on other factors, such as the weather, earth's magnetic field, the cycle of the moon and other unknown factors. This is confirmed by Peter Lindemann in his article "A closer look at Colloidal Silver" in the Research section. This may seem unscientific but I am serious, this does happen.

The only sure way of knowing if we have good batch of Colloidal Silver is when it has matured and been tested. This usually involves an initial PPM check and a laser scatter check called the Tyndall effect, after maturation has completed. The colour is the best indicator of particle size & colloid stability.

Maturation can take several hours. Immediately after production, the colloid is in a state of chaos because of the inherent turbulence cause by the electrical fields & circulating thermal currents. It takes time for the colloid to reach equilibrium which we call the "Developing" stage. During this stage, the colloid is still in its reaction vessel but moved to a cooler environment, still in the dark, to allow the colour to develop.

Although we use a low power hand laser to test the solution, the final colour is the key to quality. The colour is due to light scattering & a direct indication of particle size. We aim for sizes in the region of .001 to .04 microns (uM) which is 1 to 40 nanometres. See Wikipedia for further information on nanoparticles.

A matured batch is shown on the left of the picture compared to pure distilled water on the right. The heat pad is the white plastic item underneath, with a meter to the right to give you an idea of scale.

Any batch that fails is discarded, down the sink. We have the cleanest drains in the UK. Do be careful if you use a cesspit. It may stop working !

This particular batch failed to mature correctly, as you can see from the colour. It finally turned grey as the colloid was unstable and eventually agglomerated into large particles. This was due to a deliberately high production temperature whilst investigating the optimum temperature range.

Again, the maturation procedure is unique to us and is only possible because of the unique design of our generators. This allows us to use a modular approach to commercial production and allows extended quality checks without sacrificing production volume.

We have been manufacturing Colloidal Silver for many years and have seen many sites come and go. We thank our regular clients as they are the backbone of our business, the proof of our quality and the reason we are and intend to be, the major force behind Colloidal Silver in the UK & EU for many years to come.
