We pride ourselves on the quality of our process & our constant aim is to provide high quality at a reasonable price. We are are very encouraged by the feedback we have received and the amount of repeat orders from our customers. We will endeavour to keep our process as efficient and cost effective as possible without sacrificing quality.The quality checks are vital and explained in detail below.

We don't use commercially available generators because the integrated design does not allow for the batch to mature, which can take 4 - 8 hours. Maturation is very important as up to 1 in 5 batches can fail to reach a stable equilibrium. Also, because they are highly integrated, they are difficult to keep clean. All our equipment is thoruoghly cleaned after each batch is made. See "Why should I buy your Colloidal Silver" in the FAQ's section for more information.

I have experimented with various designs over the years and the design we use has seperate reaction vessels and removable electrode assemblies, so we can mature one batch in its vessel whilst making more in another. As mentioned above, we find that 1 in 5 batches fail our quality checks, so the maturation procedure is vital to ensure quality which is only possible because of the unique design of our generators.

We believe this maturation step unique to us. This enables us to produce a consistent high quality solution.

We make Isolated Colloidal Silver. Isolated means that the colloid contains Silver Ions (AG+) and 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 Colloidal Silver would be made using an electrolytic process using pure silver with pure water.

Two problems:

  1. Pure water doesn't conduct electricity.
  2. 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, 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 unecessary and should never be used.

We NEVER use additives.

We use fine silver (.999) for our electrodes. The picture shows two electrodes after a batch has been produced. In the centre wire is an unused piece of silver, for comparison. We purchase the silver from a UK bullion dealer and it 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.

Note the discolouration on the right hand electrode. This is normal & the electrodes are cleaned after each use. The electrodes shown are from our first test generator. The electrodes we now use are much larger but to get the whole electrode into the photograph makes it difficult to see the discolouration.

Deionised water is better but steam distilled water is the best.

Tap/filtered/softened/mineral water is totally unsuitable as it may still contain many heavy elements and could create harmful compounds during the electrolysis process.

We make our own 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

   
- Glass & PET  

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

We have experimented with the use of PET plastic for short term storage. The results are excellent for periods up to two months. We are introducing it soon as a cost effective range for high consumption users and as a refill for your Amber Bottles. PET is cheaper than glass & weighs 340g lighter so a saving in postage as well. Less weight means less energy used to move it around so we are helping the environment by refilling our glass bottles !

Although PET is a good insulator & nearly as good as glass, the bottle walls are considerably thinner and therefore will contribute to higher dielectric leakage. This is why we use glass as it will keep the particulate silver in suspension for a longer period. Ionic silver is not affected but Ionic silver isn't Colloidal Silver. If you check the FAQ's, we explain this in detail and why we think amber coloured bottles should be used.

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 large 3 litre Pyrex glass reaction vessels and six silver electrodes. Using constant current stabilised power supplies,(One per vessel) we pass a steady current through the electrodes.

We use 30 volts to start the process but when the current has risen to the optimum level, the voltage is automatically reduced to maintain this 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 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. Dependent on the ambient lab temperature, we use an external heat source to maintain the reaction between 22 - 26°C.

Although heat can decrease the time taken, it can also produce larger particles, which is why we do not exceed the above temperatures. The smaller the particles the better the quality of the Colloidal Silver. We can tell when the reaction is nearly complete because the power supply is in constant current mode and the voltage has decreased to around 8-10 volts. We use an ammeter in series to monitor the exact current.

We aim for a concentration of 10 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 child safe 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 - it is vital. 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 the maturation cycle has completed. The colour is the best indicator of particle size & colloid stability. Even with our strict process, I estimate we throw away one in five batches.

The maturation time 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 dark, cool environment. This is when the colour develops.

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).

To ensure it has completed its maturation cycle, we usually leave it 12 hours, as it will give us a good indication of its stability. After passing quality assurance, we bottle it immediately. See Wikipedia for further information on nanoparticles.

Any batches that fail are discarded, down the sink. We have the cleanest drains in the UK! Do be careful if you use a cesspit. It will 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 making Colloidal Silver for many years and I have seen many sites come and go. I thank my regular customers as they are the backbone of our business. They are 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.
