Silver Generator
Colloidal Silver has been used since the early 1900s. Not all Colloidal Silver Generators are created equal - in fact most systems on the market use a method called "Constant Voltage".

A proven better method is to generate a "Constant Current" level but the circuitry is a bit more complex - so most manufacturers don't bother. You see the "Constant Current" method must automatically adjust the voltage so that the current maintains a constant level as more and more colloid is added to the solution. You see the colloid adds conductivity so for the current to be maintained at the same level the voltage must be changed continually through the process.

There are two options depending on what type of voltage your local utility uses (choose the first one if you are in the US or Canada). The first is the 100-120 Volt standard model which is $229.

The second option is mainly for overseas folks. This is for the 220-240 Volt "Euro" model which is $269.

How many times have you seen advertisements for colloidal silver generators that promise small particles? The fact is, most units on the market today can't deliver uniformity because they use a constant voltage source to create the silver particles in the water. Our colloidal silver generators consistently produce particles between .001 and .005 microns in size.

Most Colloidal Silver Generators are difficult to use and make very inconsistent quality colloid. Finally there is a simple to use generator that turns off automatically and it won't cost you an arm and a leg!


If you are considering using colloidal silver or have already been using it - the information on this page may change your whole understanding of this most amazing substance! Bolt the door closed and block out all distractions - so you can absorb all this important information...

The key question to ask if you are thinking of buying a colloidal silver generator from someone else:

"Is your generator a constant voltage device?" If they answer "Yes" then you will be getting an uncontrollable device. It doesn't matter if the voltage is provided by a transformer/rectifier or batteries. Constant voltage generators are rudimentary and you will probably be unhappy with the device in the long run. They just aren't much good.

The problem is this: Distilled water is a fairly good insulator. With a constant voltage connected to silver electrodes in distilled water, the initial current flow is very low because the water has high resistance to electron flow. However, as the silver ions and particles start to accumulate in the water, the resistance in the water goes down from the conductive silver content now building up.

This causes the current flow to increase and as a consequence, the silver particles begin to increase in size (they are being ripped off the silver electrodes.) As more silver is torn from the electrodes, the process is accelerated until one has to stop the process because the particles become so large they begin to fall out of suspension.

If the particles of silver are truly colloidal, they will be suspended in the water because they are not heavy enough to sink to the bottom of the vessel. Larger particles are too heavy to remain suspended, so they fall to the bottom of the vessel. So, uniformity of size is VERY important. Most manufacturers do not tell you this fact because their generators are not capable of making SMALL, uniform size particles except for brief periods of time. That is, only so long as the current flow is LOW.

That is why some manufacturers tell you to put salt in the water at the start and run the unit for a few minutes only.

Adding salt to the water increases the conductivity of the water which gets the reaction started quickly. You are then told to run the unit for only a short period of time because they know the reaction will be too violent if left to run very long. This is not good. Salt in the water creates silver chloride. What we want are pure silver colloidal particles and silver ions. Silver ions are single atoms of silver that have lost an electron and now have a positive electrical charge. Our generators produce about 85% ionic silver and the balance is colloidal. The colloidal portion is what you see when you look at the electron microscope pictures on our website. The ions are too small to be seen with the microscope and most researchers and experts are convinced it is the ions that do the most effective healing.

Using salt in the water creates two or more silver products; a chloride and a colloid.

Even more chlorides can be produced, depending on what was in the salt. As you may know, sea salt contains almost all minerals known to man. This is because all streams and rivers flow into the sea and carry the minerals they come in contact with into the sea. And that is why the sea water is mineralized. When one dries seawater to get the salt from it, they have a representative sample of what has flowed into the sea. The salt is composed of all the minerals the fresh water has picked up during its travel to the ocean.

So, you can see using sea salt would be the worst material you could use to make the water conductive. These minerals would combine with the silver to form many different silver chlorides.

That is NOT what we want. We want only ionic silver, colloidal particles and pure water to be in the final product.

All the particles coming off the positive electrode as ions are electrically charged the same, and like charges repel. Therefore the particles try to stay equidistant from each other in the dispersion. The colloids can be seen by shining a strong, narrow beam of light through the suspension. The beam of light will reflect the light off the silver particles and it will appear as a foggy beam. With the light off, the dispersion will be quite clear. The best way to see this effect is to use a laser beam. The small pocket models work quite well for this purpose. If you use a flashlight, try to do it in the dark and you will get the best result. This is called the Tyndall effect.

Most units on the market today use a voltage source which is usually between 27 and 36 volts D.C. This can be supplied easily by using either 3 or 4 - 9 volt batteries in series to produce the voltage. This is not a problem. In fact it can be very useful because the generator can be used anywhere at anytime and not be dependent on the electrical power system. If one is on an outing, boating, traveling or living where house wall current is not available, it can be a boon to have a battery powered unit.

The problem with the battery powered units and most of those powered from the wall current is, the voltage is not reduced as silver is released from the electrodes. This causes the silver to be released from the electrodes at a faster and faster rate as the water becomes more conductive. By reducing the voltage as the water becomes more conductive the current remains the same and the particle size is kept constant. This is what we strive for when making colloidal silver.

What is the proper way to make colloidal silver?

It is to use a power source that can reduce the voltage in order to maintain current flow at a preset maximum value.

This is called a constant current source. Remember, the voltage only makes the current flow. It is the current that makes the silver particles come off the electrodes. If the current is too low, no silver particles will be formed and if there is too much current flow, the particles will be too large and will not be colloidal. It is a tricky combination but when the current is dialed in just right - and held constant - the best colloidal silver with small ionic particles is made.

I have one of the only colloidal silver generators on the market which uses a constant current source. Our top of the line model Model 6 Auto has a built in stirring motor to eliminate agglomeration and also has an automatic shutoff circuit and a variable PPM control so you can just set it for the strength you want and when the light goes out it's ready to use. No clipleads or external electrodes to bother with.

There are two options depending on what type of voltage your local utility uses (choose the first one if you are in the US or Canada). The first is the 100-120 Volt standard model which is $229.

The second option is mainly for overseas folks. This is for the 220-240 Volt "Euro" model which is $269.

I prefer to not sell the colloidal silver liquid because I know it is better for you to make it yourself. Having a colloid generator is an investment for your well being that is much better than having to search for the colloidal silver when you need it. And you can make it any strength you want. Generally, when you buy colloidal silver water, you never can tell the strength of the solution or what other products may have gone into making the product.

There are a lot of colloidal silver generators on the market. In most cases, what you get for your money is a box with three or four 9 volt batteries connected in series with a switch to turn it on, a light bulb in the circuit which will light up if the terminals are accidentally touched together (it acts as a fuse which won't blow in case of a short circuit), a couple of leads with clips and two small gauge silver wires. Some are the equivalent of this but designed to plug into an AC outlet to save your batteries, but they are still constant voltage and not constant current! You really don't get very much for the amount of money you pay.

Our generators are NOT battery operated. They work off regular house current and have electronic circuitry which allows our units to make colloidal silver which is uniform in particle size and is consistent.

Our Model 6 Auto generators contain a printed circuit board, transformer, full wave bridge rectifier, diodes, resistors, capacitor, transistors, a stirring motor and other electronic components. In addition, our electrodes are 1/4 inch wide and 5 inches long and are made of 28 gauge .999 fine silver. They have about 2 1/2 times the surface area of the wire electrodes supplied by others. This reduces current density by the same factor, resulting in smaller particles.

Our Model 7 Pro unit is considerably more sophisticated and uses many more electronic components than the smaller models. Not only does it use constant current but it uses a timing circuit and switching relay to reverse the electrode polarity at regular intervals. This allows the electrodes to be self cleaning which is just one more advanced feature not found on other units. Normally the cathode (negative electrode) will attract some of the positively charged silver from the water during production. This buildup or coating acts as an insulator and will impede the process unless it is removed. By reversing the polarity any buildup is repelled from the negative electrodes when they becomes positive in charge. The elemental silver will then fall to the bottom of the vessel because it is not colloidal and is too heavy to stay suspended. You will not have to stop the process to clean the electrodes with the Model 7 Pro even if you were to make 50 gallons at one time. This is a wonderful feature.

For those of you who may have times of no electrical power and wish to be able to make colloidal silver, we offer a modified unit that can work off both house current and external battery power. These units will work with any DC voltage up to 40 volts. This means you can use a 12 volt auto battery or as many as 4 - 9 volt transistor radio batteries in series as the voltage source. The internal current regulator will still work the same as if the unit was powered with alternating current from the wall. These units are equipped with an extra power cable and clip leads to connect to the voltage source and are also protected against reverse current in case you connect it to a battery incorrectly.

What we offer is a "constant current" generator. Battery operated units are basically a "constant voltage" device. What this all means can be broken into two explanations.

Constant voltage generators operate as follows... (why they aren't much good)

When an electrical source of
voltage that is fixed in value such as 27 or 36 volts (the voltage supplied by 3 or 4 - 9 volt batteries in series connection) is used to generate colloidal silver, the voltage is connected to the silver electrodes which are in the water. A small amount of current then begins to flow. At this point the current is generally about one quarter of one milliampere (a milliampere is a measure of current flow). This allows some of the silver ions to be released from one electrode while hydrogen gas is formed and released from the other electrode. As the silver is released into the water, the conductivity of the water increases, allowing more current to flow. This in turn allows more silver ions to be sintered off the electrode. So far so good. But what happens very quickly is this:

The increased current flow allows the metal to be deposited into the water at a faster and faster rate as the conductivity of the water is increased by more silver being released. This is a vicious cycle because in a very few minutes the current passes the point where small colloidal particles are generated. Particle size is determined by many factors; one of them being current flow or more properly current density. Once the flow exceeds this critical point, you must stop the process or risk producing large particles. These particles are NOT colloidal. They will sink to the bottom of the liquid and will generally not stay in suspension. Constant voltage generators cannot be left on for long without producing large particles.

If you ingest larger particles or silver salts in liquid such as silver nitrate you take the chance of acquiring a condition know as
argyria On the other hand, colloidal silver particles are so small they do not cause this condition. They are continually being excreted in your bodily waste. There has never been a case in which argyria has been attributed to ingestion of colloidal silver. Please see our link to "Where does the silver go when you drink it" by Dr. Roger Altman.

Constant Current Generators work as follows... (why they work so well)

The voltage source may be the same or higher as
constant voltage generators at the beginning of the operation but the similarity between constant voltage and constant current generators diverges rapidly. As the current flow begins to increase with increased water conductivity, the "constant current" regulator begins to reduce the voltage in order to keep the current at the desired amount of flow. With the voltage being reduced in order to keep the current constant, the silver particle size remains uniform. As the water becomes very conductive, the voltage may be reduced to as little as 5 or 6 volts to maintain the desired current flow. With this type circuit, one may leave the generator connected to the electrodes and not worry that "runaway" will occur. You may leave the generator on until the strength of silver in parts per million (PPM) is reached and be assured the particle sizes are uniform and colloidal. Of course we are speaking of practical limits here. This is the secret of repeatable production of colloidal silver. Constant current equals constant size particles. Our generators can produce up to 50 PPM. Any concentrations higher than this require the additions of stabilizers in order to prevent fallout. However, CS made over 15 PPM will usually agglomerate so we recommend you do not make it over that strength. Our automatic generator (Model 6 Auto) with stirring motor can make up to 20 PPM without agglomeration.

If the particles are as small as can be made and also colloidal, the water will be clear and will also show the
Tyndall effect. If they are larger, the water color will shift toward yellow because of agglomeration. Still larger particles appear red; then green and the blue ones are the largest. The proper color for colloidal silver water is clear. If it is clear and has a weak Tyndall effect, the particle size is as small as can be made. That is the best way to know you have colloidal silver water. Make it yourself and then you will know and see what we mean! The proof is in the clear color and the Tyndall effect. Of course you can also test it using the PWT meter to determine the total PPM.

With our Model 6 automatic generator you just set the dial to the PPM (parts per million) desired and wait until the unit shuts off automatically and you will have the best colloidal silver that can possibly be made. It will always be crystal clear and have a weak Tyndall effect (that's good!).

There are two options depending on what type of voltage your local utility uses (choose the first one if you are in the US or Canada). The first is the 100-120 Volt standard model which is $229.

You can produce about 3.5 PPM per hour in a pint (16 ounce) vessel. Double the time and you double the strength, etc. If you produce CS under about 10-12 PPM, it will be clear because the particle size is as small as can be produced and reflects no color. Over 12-15 PPM the CS will usually become pale yellow colored over a 24 hour period. The reason for this time lag in color change is the particles are becoming more evenly dispersed in the solution and at the same time some of them are agglomerating. There would be less agglomeration if the water had been stirred during production. They rearrange themselves to maintain the same distance from each other by virtue of their electrical charge. Remember, "likes" repel each other. Once the particles are completely and evenly dispersed, the color will be seen. These particles reflect yellow light while clear CS will not reflect light because the particles are so small. The yellow color comes from the fact that higher PPM CS allows some of the particles to agglomerate together to form a slightly larger particle, allowing yellow light to be reflected while absorbing all other colors. Agglomeration means some of the silver atoms are starting to share electron rings.

The bottom line is this:

Make your CS clear and you will be getting the largest amount of individual silver particles per unit measure of water. As an example, 1 milligram of silver dropped into 1 liter of water is equal to 1 part per million by definition. If you could turn that 1 milligram into 1 million individual silver particles and disperse it in the water, the PPM is still 1. However you now have many more individual pieces of silver in the water to attack bacteria and viruses. If you could divide that 1 milligram of silver into so many pieces they barely reflected any light, then you would have the optimum amount of silver per unit measure of water. Typically those particles are about .001 to .005 microns in diameter. A micron is one millionth of a meter (or 26 millionths of an inch) so .001 microns is about 1/1000 of 1/1,000,000 of a meter. Pretty small particles indeed. Our generators typically produce particle sizes ranging from .001 to .005 microns. Ask for our electron microscopy photos to see proof.

You may also observe this effect by directing a pocket laser beam or strong narrow flashlight beam through the liquid during the dispersion phase. The beam will become more visible as the particles are evenly dispersed, allowing the light to reflect off them. This is called the Tyndall effect.

Another factor in colloid production is the surface area of the electrodes. If one uses wire as the electrodes as most manufacturers do, the surface area is quite small. As an example, 14 gauge wire, which is what most units are sold with, has a surface area of approximately .8 square inches if it is submersed 4 inches in the water. Two wires will give approximately 1.6 square inches of wetted surface area.

Our electrodes are .25 inches wide and .013 inches thick. If they are submersed 4 inches, the total surface area will be 4.21 square inches. This is 2.5 times the wetted surface area of 14 gauge wires. Therefore the current density of 14 gauge wires will be 2.5 times higher than the electrodes we use. What this means is, the amount of silver released using our electrodes will be so spread out over the surface of the electrodes, it will be releasing at a slower pace. If the silver is released more slowly, the particles are smaller. They will also be more uniform in size because of the constant current regulator and stirring. The result is a more uniform, small particle size colloid.

If one used a constant voltage source, such as the typical box with three batteries or a machine that uses a wall transformer to provide a constant DC voltage, the silver would begin to be ripped off the wire electrodes very quickly because of the high current density which continues to increase during production. The resulting silver particles would be a non-uniform size and would be composed of small to large size particles as the current began to rise with time. The color of the water would be yellow, red, brown or muddy looking and silver sludge will begin to drop out and fall to the bottom. The particles of silver are getting too large as the current begins to run away and rise dramatically.

Why Bother with anything else? Our units are so easy to use!

You may also have noticed that other manufacturers seem to have different techniques for making the colloidal silver. They may ask you to add salt, heat the water, throw the solution out if it becomes muddy and start over, run the unit for short periods of time only and other requirements. None of this is necessary if one uses a "constant current" generator. All the variables are accounted for automatically.

If the water is warm, the initial constant current will be reached a bit sooner than if cold water was used and timing may start a bit earlier. The water temperature will not control timing or strength of the solution once the target current is reached. Target current is low, so it takes very little time before the colloidal particles are being formed.

Salt is unnecessary and is a detriment to proper operation.

NEVER use salt. It will produce silver chloride which is a silver salt. We are looking for the metallic silver particles and ionic silver only. A constant current generator will make ONLY electrically charged ionic particles and metallic colloids and it does NOT need additives to start the process.

Proper timing is necessary to produce the quantity of silver in solution but it is NOT necessary to stop the current flow after a short period of time as most units require. Using those battery powered units, which are constant voltage generators are the equivalent of driving an automobile with the gas pedal stuck to the floor. They will run away with you and are uncontrollable. Constant current puts you back in control. Don't settle for less than the best.
