the majority of particles are concentrated in the 1 - 10 nm (nanometer) range. Particles that are smaller than 1 micron 
is the requirement to accurately match the true definition of being a colloid. A micron is one billionth of a meter.
What is the difference between Colloid Master AC and the Colloid Master Universal?
The differences are many, however the main difference is also the reason for the name given to each model:

1. The name Colloid Master AC signifies that it can only be powered via 110 Volts AC.
2. Colloid Master Universal signifies that it can be powered by multiple power source types, such as 110 Volts AC, also 220-240 Volts AC, 
or with the optional regulated DC adapter (Item #13) it can be run via 12 volt cigarette lighter receptacles or RV outlets. It can also be 
powered via the terminals of any 12 volt battery or via the load connectors on a 12 Volt Solar system. 
Although the enclosures of both models of the Colloid Master look similar, the circuitry inside is completely different for each model of the 
Colloid Master.
The Colloid Master Universal is a more rugged industrial design in terms of the circuit board and overall construction. It is made tougher and is more 
durable in order to withstand off-grid, remote-location, in-field use, as well as being better able to tolerate the rigors and abuses of being shipped 
long distances.
Either Colloid Master is a good choice, each comes with a 30 day money back satisfaction guarantee, as well as a 3 year warranty.
The important thing to know is that the silver dispersions created with either unit are nearly identical.

We have stored the silver dispersion in clear bottles in a dark storage area In our facilities for several years with little or no change in the PPM originally tested when stored. The self life should be many years, based on current observations.

More information and things to consider:

A question that seems to come up frequently these days, is whether or not the Colloid Silver Master is a constant current device. The answer is: yes, but it is more complex than that. To call it simply a constant current device does not justly describe the complexity of the process. The current and voltage is adjusted to the optimal levels by the device. It also monitors the solution and automatically shuts off at the approximate parts per million it is adjusted to by the user.

The Colloid Silver Master does produce a constant current, that is also modulated. Don't be fooled by the misinformation out there, and those that try to get you to believe that all colloidal processes are basically the same. Not true! A simple 9 volt battery operated unit, or units with simple cheap linear power supplies and no true control cannot be compared to the Colloid Silver Master. These folks are selling you $ 5.00-$15.00 worth of parts slapped together and sold for $ 35.00 to $ 80.00, do you believe you are getting a deal?

There are apparently marketers of products that sit on top of a glass etc. that are a very simple 9 volt battery design with no control over the type of colloid that is produced, they try to get you to think that it is a superior process if there are no wires to hook up. What is more important is whether or not the proper amount of voltage and amperage is reaching the electrodes at a given stage in the process, regardless of how the electrodes connect to the colloidal silver generator.

The conductivity of the liquid changes throughout the process because the conductivity of the water increases as more silver is dispersed into the liquid (water). If the equipment is not designed to compensate for these changes the size of the particles will not be consistent. We typically spend more money on the parts that we use to make our generators than others are charging for the retail cost of the simple generators they are selling.

Regarding stirring, the Colloid Silver Master (R) employs a bi-directional current pattern to the electrodes. This causes the particles to be moved into the solution without the use of a stirrer. We addressed this issue long before others even thought to consider it. Research in this regard is on going.

We could sell a cheap unit, we don't because we believe that it is too important that we provide the best possible equipment, at the best price. Our colloidal silver generator is not cheap, it is inexpensive relative to the cost of parts and workmanship and general cost of doing business. We only sell a quality device backed by our 30 day money back guarantee and 3 year parts and workmanship warranty.

Colloid Silver Master Overview
Our goal has been to create a colloidal silver generator (scientific instrument designed for dispersing metals into liquids) that produces consistently small silver particles. Below is a brief description of the Colloid Silver Master. To make a long story short, it is a sophisticated device that is simple to operate. It has an adjustable Parts per million / shut off dial. The Colloid Silver Master starts by simply pressing a button, then forget about it. It will shut it's self off when the process is done.

The Colloid Silver Master incorporates a built in water quality test function.

The Colloid Silver Master Colloidal silver generator, monitors the condition of the liquid throughout the process, once the proper PPM is reached it shuts off automatically. The user chooses the PPM setting. The Colloid Silver Master is adjustable, it does not use a simple timer or a meter for manual shut off. The professional design incorporates complicated features into it's circuit design that automatically modulate the current in order to create superior dispersions.

The Colloid Silver Master makes one quart batches as a standard size batch. The user could also make 8 ounces or a gallon. What will change will be the amount of time required to make the colloid, surface area of electrodes needed (length), and distance between the electrodes. We have had success in making one Gallon batches using a 1 1/2" inch distance between electrodes.

Experimentation is possible with the Colloid Silver Master. Although we have established a recommended electrode distance and amounts of water used, it will allow for changes in the process.

It is not necessary to use lab glass to make colloid with the Colloid Silver Master. It was designed so that it can be used with a common canning jar. Standard jars made by Ball (R), Mason (R), Kerr (R), Atlas etc. all work well.

Note: Do not use wide mouth jars, a standard jar as we suggest has a 2 1/2 inch opening at the top. Notice the electrodes are placed on opposite sides of the jar. The electrode contact wires are pre installed into the Colloid Silver Master with copper clips on the ends for attachment to the electrodes. Notice a small tab of the electrode faces outward to attach to (See picture above). The tab can also point downward and may ease keeping the electrodes straight down in the jar once the electrode wires are attached.

Points to consider when making colloid with the Colloid Silver Master

Parts per million
The dial of the Colloid Silver Master goes from 1 to 10, this does not represent parts per million, the Colloid Silver Master comes with an example PPM chart that illustrates approximate PPM. below is the correlation to parts per million. Recent tests show that using 32 ounces of water that the recommended PPM production range for the Colloid Silver Master Model 777 Universal AC is 5 to 20 PPM.

The dial indicates from 1 to 10 so that it is not locked into use for silver only, experimentation with other metals such as zinc and copper for example. The automatic shut off feature is not expected to function the same for other metals. Our focus has been with regard to silver.

Note: Based on research, it has been our long standing opinion that the optimal range for silver is 13.5 to 17 PPM. There are many factors that we took into consideration when making this decision, including; stability, quality and integrity. Silver dispersion is in our opinion, is in essence saturated at 13.5 to 17 PPM, although higher PPM can be forced or attained, our research has convinced us that forcing higher PPM may compromise the quality, stability or integrity, and in effect causes it to be less balanced.

If you are interested in monitoring the PPM of the colloid you produce with the Colloid Silver Master the most precise way is with proper lab equipment, although a quick relatively accurate and inexpensive way is to use a PWT (pure water test) meter.

A PWT meter (by Hanna Instruments etc.) measures conductivity, this data is then interpolated to reflect the parts per million. Although there is no inexpensive device that directly measures ppm, we have found that this method is a very reliable method to approximate the ppm. It is accurate to within 2 percent full scale. The interpolation of the conductivity to PPM translates to approximately less than 1 PPM full scale regarding accuracy.

The most sensible method to validate your meter and the strength of the dispersion, is, once you are accustomed to using the equipment, and know what the most common setting is that you use, then send a sample in to a lab to determine PPM of silver. The reason is, the meter is an inexpensive spot check technique, accurate lab tests range from $ 35 - $ 200 per sample. The Hanna PWT meter it is more sensitive to ions, and the solution is a combination of ions and particles. Both particles and ions register by the meter, but at differing values. Therefore water quality and other factors effect the overall results.

Note: We do most research with the Colloid Silver Master using setting 5.5 but we also use settings 5, 6, and on occasion setting 7. Gallons are usually made at setting 7 or 8 with a 1 1/2 inch electrode distance.

How long does it take to produce the colloid?
The normal range of time it takes to produce colloid is 3 to 8 hours. You will get to know what to expect after making several batches, and with experience over time. The manual explains this in more detail.

The time required to produce a colloid at the same setting may vary slightly from one use to the next, even when using the same water, but the resulting colloid is predictable, small particle size is maintained and as a result the dispersion is relatively stable. The PPM is very repeatable. We have batches in storage from over a year ago that has remained the same as when it was stored, or at least to within the accuracy of the PWT meter, approximately 1 PPM variance.

As mentioned before, the Colloid Silver Master functions the same way every time it is used, however; there are other factors to consider. Changes in environmental conditions effect the process such as ionization in the air that is transferred to the container during the process, as well as forms of energy directed at Earth from solar events. That is why we do not use a timer, we have found that, in order to maintain small particles and to force unwanted byproducts created during the process out of the sol a precise adaptive process is required.

During the process there is water and silver interacting with current, silver atoms are dispersed into the water also some silver combines directly with oxygen (silver oxide) the dark color on the electrodes. Some silver also combines directly with hydrogen, and appears as a silver white substance. The Colloid Silver Master is designed to allow the unwanted particles to accumulate and fall out of suspension to the bottom of the container. There will also be accumulation onto the electrodes. The finished colloid should be filtered using filter paper. Filter sources are included in the manual. The electrodes are cleaned before each new batch using the included cleaning pad.

The Colloid Silver Master was designed to be used with a common canning jar. Lab glass is expensive and not required for this process. When the electrodes are suspended into the jar by the rim of the jar, and the electrodes are on opposite sides of the jar, there is then a 2 1/2 inch distance between them. The process will speed up considerably if the distance is reduced to two inches. This can be accomplished using a plastic lid that fits the jar, such as from a mayonnaise jar, cutting 3/4 inch slits in the lid at a distance of 2 inches apart. Each electrode can then be slid into the jar and a distance of 2 inches, or other experimental distances for different metals can be maintained.

What are the reasons that production time can vary?
Production time and parts per million in general will vary primarily due to factors such as water quality, power source, having the jar too close to 110 - 220 Volt AC power lines or anything that creates moving magnetic fields such as a 220 Volt AC motors e.g. clothes dryer etc.. Surprisingly one of the biggest concerns is the SUN, in particular solar events. This may seem odd at first, however; we have monitored numerous solar events that correlate to observed changes in the colloidal production time and resulting colloid for more than five years at the time of this writing.

The phase of the Moon may have an effect on colloidal silver production. Please read: Lunar Influence on the Electrochemical  Production of Colloidal Silver 


Solar events are a big issue, especially during this time. This is due to the fact that we are in an extended solar maximum period, the sun is sending lots of high speed particles such as x-rays our way. We have noticed that if the events are very dramatic, the process as well as the colloid can be effected. It is easy to visually identify the effects caused by solar occurrences such as coronal mass ejection that are directed to and effect Earth. This is discussed in the manual.

You can monitor the solar events yourself here: Here are some links for you to access a very good data base for monitoring solar events and the geomagnetic field:

About the use of salt
We do not use salt for colloid production, it causes variations in the process and the resulting colloid / dispersion that our opinion is undesirable. Instead we suggest the addition of 2 to 3 ounces of previously made colloid to the fresh water before starting a new batch, this will decrease the time needed to complete the process. Using previously made colloid as a STARTER is the optimal method. The use of previously made colloid as a starter will take less time for the process to be complete, but does not generally increase PPM.

About heating the water
Heating the water is not required with the Colloid Silver Master, it is designed to work at room temperature approximately 72 degrees F, this allows the process to proceed as it is designed to. Maintaining a warmer temperature, such as on a coffee mug warmer is known to speed the process.

Important information about colloid production!
It is best to keep the clear glass canning jar container or lab glass that the colloid is being made in a dark place or covered to protect it from exposure to light.

The process seems to be taking too long, how can I check how close it is to being finished?
While the process is active the green Processing light (led) will be on. The process is complete when the green light goes off and the red Process Finished light (led) goes on. To check the progress of the process you can turn the PPM adjustment dial down toward the number one setting on the dial and note where the GREEN light goes off. If the green light goes off with only a very slight movement of the dial it is so close to completion that when this happens we stop the process and consider it done. If you find that it still has a way to go, it is a good idea to clean the electrodes, reset the dial to the desired PPM setting then press the start button to restart the process.

What happens when the process is complete?
The colloid will go through a dispersion process during the first 36 hours after being made approximately). During this time the particles create stable associations, at completion the particles are in a stable state, relatively. It is important of particular importance to keep the colloid out of the light while it is processing and for approx. 36 hours afterward. Storage of the finished product should be in a clear glass container kept in a dark location, amber glass or a ceramic container that does not allow any light through.

How do I know the distilled water I use to make the colloid is pure?
Since the Colloid Silver Master was designed in essence to monitor PPM, it can be used to pre test water quality. To test the distilled water simply fill the jar with water, place the electrodes into the water and suspended from the rim each electrode on opposite sides of the jar. Plug the Colloid Silver Master into the power, turn the PPM adjuster to the highest setting, press the start button, then turn the dial down toward the lowest numbered setting and observe where the green light goes out. It is best if the green light does not go off, this means the water is as pure as possible.

Trouble shooting: The green light (process running LED) won't stay on, why?
As described in the water test above, the Colloid Silver Master knows if the water is pure or not, if the dial is turned to the highest setting and when the green start button is pressed the green light goes on while the button is pressed, but it then goes off when you take your finger off of the start button. This normally indicates either highly contaminated water, rarely a dysfunctional unit.

The solution is to first confirm water quality with a PWT tester, or try another brand of water. If you are using your own distiller replace the (polishing) filter. The polishing filter is the carbon filter most often located in the spout of the distiller. How can I be sure it is not the Colloid Silver Master that is the problem?

The first test is power up, with the electrode wires NOT attached to the electrodes, plug power supply in to the Colloid Silver Master, the red test light should go on to show proper functioning. Press start. If you find that the green light will not stay on, and the electrodes wires are not touching each other, nor are connected to the electrodes, then the unit may not be working properly. If the green light stays on, then the problem is almost certainly the water quality. Remember, use only distilled water.

The Colloid Silver Master standard electrodes are 6 X 1/4 Inch 99.99 pure fine silver. Each set of electrodes will last several years under normal use. An expected amount is 75 - 100 quarts per set of electrodes (at higher settings). Electrodes will last for years, depends on setting used, amount made and how often. Example only!

About the color of colloidal silver?

There is a lot of information about colloidal silver on the web from both sides of the fence, that is often not backed by true knowledge. There are numerous issues we could address. Let's start with the issue about the color that colloidal silver should be. Some say it should be clear, some say it should be deep gold to amber or even a reddish tint in higher PPM states. What is being over looked is what type of these potential colloids produce the best results for a given purpose. We are most interested in research that focuses on the destruction of pathogens. keeping the colloid at low PPMs to avoid or eliminate potential toxicity issues, yet at optimal levels for pathogen destruction is the objective for serious research.
Due to ongoing research, we are convinced that a colloidal silver that has a negative surface plasmon absorption band is the best for these purposes.

To make sense of the colloidal silver color issue I will quote from a paper by "Paul Mulvaney - Berich Strahlenchemie, Hahn-Meiter institut, D - 1000, berlin, 39, Germany" Titled " Colloidal Silver: Charge-Transfer Process and Photochemistry"

"In this report we present some recent results on charge-transfer and chemisorbtion process on colloidal silver. It has been found that the surface plasmon absorption band of colloidal silver, which is responsible for the yellow color of silver sols, is very sensitive to changes in the state of the colloid surface."

"The positively charged sols have a yellow-brown color, while negatively charged sol particles are a pale yellow.)"

" The absorption band maxima is shifted to shorter wavelengths when the particle becomes negatively polarized. Thus, the optical spectrum can, in principle, be used to determine whether a silver sol is negatively or positively polarized." "One difficulty is to determine the wavelength of the absorption maximum when silver is uncharged (i.e., at the so-called plasma null point or PNP.)" [End quote]

Colloidal silver can appear to be light yellow to yellow-brown, not because of excessive oxidation as is sometimes reported, the consideration is the surface plasmon absorption band polarization. The color is due to the light refraction of the yellow to yellow brown part of the light spectrum. Colloidal silver can also appear as a clear solution such as when the colloid is uncharged, referred to as " stoichiometric".

It is possible for contaminants or oxidation to be a factor regarding the color of colloidal silver, however; generally speaking the colors described above are a result of polarized charge contained in the surface plasmon absorption band, not contaminants or oxides.

Another issue that takes a beating on the Internet is particle size and metallic state. There are comments made that colloidal silver if it is not clear is a toxic heavy metal, however the truth of the matter these comments are not backed by provable data. The truth is, science is not as clear about this issue as some suggest. Quoting again from the above source "A quantitative understanding of size-dependent changes in the surface plasmon absorption band may eventually permit us to decide at what point silver clusters become metallic." [End quote]

As you can see from the above information that, although science has established theory regarding issues about various states of matter, the truth is, the lines are not as clear as you might expect. In particular metals that fall into the category of elements know as the transitional group, (such as silver) are very anomalous, in that, they have attributes that are drastically different when in the atomic or sub-micron colloidal state, than when crystallized into the common metallic form. Science is not in agreement about where the line is drawn between one state and another, science is in search of ways to quantify with accuracy at what point colloidal silver clusters are considered metallic.

Our difficulty at the moment is to attempt to give the reader an understanding of why we have chosen the process that we use. We have reason to believe that that a wide range of particle sizes should be considered. Apparently nano-clusters of silver have electrons are actively in motion on the surface of the particle, this causes the particles to attract water molecules which result in changes to the water its self, such as a reduction in surface tension, and the potential for structuring of the water molecules. The human body requires a reduced surface tension of water in order to absorb nutrients and expel waste. The water that surrounds cells has a surface tension of approximately 45 dynes. Unfortunately tap water is normally about 70 dynes, that means the body has to reduce the surface tension of the water in order for it to be used effectively to feed and cleanse the cells.

Our first goal is to create a dispersion that has a reduced surface tension, which is noted to be a phenomena of particles smaller than the normal metallic state. Again to make sense of this I will quote the above source. " The onset of plasmon absorption is considered to delineate the boundary between non-metallic and metallic behavior. Clusters are characterized by sharp absorption bands and the absence of collective oscillations."
[End quote]

In simple terms, the point at which the metallic behavior is determined is that the particles do not have "collective oscillations" also referred to as Brownian motion, the attribute that allows the particles to be suspended in the sol. A sharp plasmon band does not refract the yellow color as the smaller than metallic polarized particles do.

The exact reason that certain types of colloidal silver have been reported to kill pathogens is not yet fully determined scientifically. Our tests and observations to date, lead us to believe that the reduced surface tension allows the particles easy entrance into cells as one consideration. The observed selective destruction of pathogens is another issue that needs consideration. The most likely explanation will address photoelectron emission by sub-micron silver particles, chemisorption, the presence of negative hydrogen ions and Oxidation / Reduction Potential (ORP) existing in the negative range.

In other words the process for selective pathogen destruction resulting in potential antibiotic type effects will likely be found to be a result of combined features, such as decreased surface tension, which allows the particles to easily move into the surrounding cell fluid, or into the cell. The presence of photoelectron emission that may be found to emit a type of energy likely to be hostile to pathogens but desirable to healthy cells. Chemisorption of anions or other energies effecting pathogens in such a way that it result in the instability or destruction of the pathogen structure or processes. Other considerations could be the effects of zeta potential or other yet to be recognized energies emitted from the colloidal particles as well as the influence and presence of negative hydrogen ions on the surface of the colloidal silver clusters, especially as they relate to the attraction, structuring of water molecules and decreased Oxidation/Reduction Potential (ORP).

As you can see, the issues involved are more complex than some who have not considered these matters would have you believe. The few comments made here are greatly simplified for this presentation.

I hope the above information has helped to clarify some of the issues and concepts involved.
