Colloidal Silver Generators

Colloidal Silver Generators: Electrically Isolated Silver (EIS) is currently not specifically endorsing any particular model of colloidal silver generator. Rather, this section has been designed to give the interested individual the information necessary to make a an excellent purchase decision.

We now only list a few generators. This is mostly due to the aggressive marketing hype out there, not necessarily because other equipment is not good. We would much rather people take the time to learn what makes good EIS, good EIS, and make their own choices!

Size Matters

The first decision anyone interested in purchasing a colloidal silver generator must make is regarding the capacity. How much colloidal silver will you need? Just enough for yourself and a small family, or more?

The small units on the market are very affordable, but only produce enough colloidal silver for personal use. Most will easily generate enough CS for two people.

It is easier to produce a high quality batch of colloidal silver with a small generator, primarily because it is easier to manage all of the variables of colloidal silver production. The quality of an EIS (Electrically Isolated Silver) is dependent upon the acutal surface area of silver in the water. Smaller electrodes can be used without much consequence with smaller colloidal silver generators.

We currently don't have a recommendation for high capacity colloidal silver generators. Educate yourself completely before making a purchase! There are pitfalls with generators that use HVAC, and generators that recommend using a conductive agent in-process!

Shape, Configuration and Placement of the Electrodes

The simplest generators use straight, pure silver electrodes (all silver used must be at least 99.99% pure) placed directly into water; often times with the electrodes spaced haphazardly. While this method works, it is not ideal. Furthermore, some units are sold with the electrodes bent with top hooks, so that the electrodes sit on the edges of the glass containers. This is not correct, as it changes the conductivity of the water around the rim.

Therefore, pay very careful attention to the electrode configuration. The more surface area of silver in the water, the better the production process. The placement of the electrodes is also important. The electrodes should be in the middle of the production vessel. The spacing of the electrodes is also critical. For units with no circulation, the electrodes should be evenly spaced, with an equal distance between electrodes and the sides of the "brewing" container.

What We Won't Include

  • We won't include companies who sell colloidal silver generators that use hype to promote sales (even if their generation device is of acceptable quality)
  • We won't include companies who promote making lower quality colloidal silver. This includes generators that use air bubbling devices to stir (introduces contaminants and nitrogen into the distilled water). It also includes companies that promote using a baking soda, salt, or hydrogen peroxide primer (H2o2 used during the production phase). It also includes companies that promote "golden" colloidal silver as being superior to EIS that is crystal clear.
  • We won't include companies that produce colloidal silver generators that are, in essence, the most basic colloidal silver generator possible.

Coyote ZEnterprizes Silverpuppy - Thermal Series 2 Colloidal Silver Generator

  • Priced at $160.00, features low current use, thermal convection stirring, unique electrode configuration, unique PPM calculations for higher PPM brews

Sota Instruments Colloidal Silver Generator - The Silver Pulser and the Silver Pulser Lite colloidal silver generator

  • Priced from $280, Sota features a low constant current, sleek engineered generator which doubles as a bio-stimulator, uses .9999 silver, with SEM and antibacterial studies available.

Biophysica Colloidal Silver and Gold Generators - CS2A, CS3A and CS12A - colloidal silver generators

  • Constant current colloidal silver generator with 12 current settings, motorized stirring, and automatic current stepping (adjusts the current automatically to control the electrolysis process). Models priced from $700.00.
  • Time kill studies done - 4 and 8 minute laboratory tests show that the Biophysica Generators perform excellent.
  • Ph analysis reads PH 6.96, very close to true nuetral.

Atlasnova Colloidal Silver Generators - Currently offers four colloidal silver generator models priced from about $80 to $270. Unlike the more automated units, these are more "geeky" colloidal silver generators.

SIS Machines - Silver Iontophoresis Devices - Based out of New Zealand, SIS has developed equipment that delivers silver ions into the body's tissues via an electrical current and silver nylon dressings. No doubt based on the work of Dr. Robert O. Becker and Dr. Bart Flick, these unique and amazing devices are useful for wound healing and infection treatment.

i have used Pro sg 7 silver generator in BOTSWANA with its Hanna tester,it produces good silver solution,please if you have sg 7 silver generator send me quotation.

I wonder about The Silver Edge generator??


...we haven't reviewed this unit.  Having taken a cursory look at the website, it seems a bit over-promoting.  After 5 minutes, we couldn't find the exact technical specifications of the unit to do an initial comparison at all.

SilverSeas says...

...the Silver Edge doesn't look like a "bad" unit. That said, they use the most undesirable "water agitation" method out there: Aeration.

While the aeration does achieve what it is designed to, there is no reason to pull nitrogen and other contaminants from the air into the water, just to avoid having to use constant current technology.

I do like the slow brew methodology, however. The electrode configuration could use a lot of work. The Silver Puppy electrode configuration is much betterf.

Robin (Lebanon, Pennsylvania, US) says...

Thank you! I'm a bit overwhelmed by the generator choices available. I appreciate your response to help narrow down my search.

Ode Coyote (Moncure, North Carolina, US) says...

A customer brought a Silver Edge unit by one day for me to crack open and evaluate.

The Silver Edge gen limits max current to 40 milliamps with a resistor [so it won't catch fire if you short the electrodes?]

The innerds are quite primitive and construction shoddy with a seal so you won't take a look inside and find 1 small transformer, 1 partially disassembled fish tank pump, 1 bridge rectifier of some sort, 1 LED, 1 resistor, 2 electrodes.

The external timer references nothing.

Surprisingly, it actually did 'work'..Looks like all those air bubbles help lower current draw by establishing longer winding pathways between the electrodes.

It takes a HEAP of wading through hype to even find that $250 price tag. [was $400 a few years back?]


Thanks for the evaluation Ode...  There is a BIG reason why, for example, mesosilver only produces low PPM silver colloid products (nano silver).

The science is pretty much in (pub med research documents):  The smaller the silver particle with a jagged-edge shape, the more cytotoxic the particle is.  With most EIS production units (like yours), people don't have to worry since the "brew" is predominantly silver ions.  But the higher the particulate content concentration, the more this becomes an issue.

The Silver Edge is one of those situations of someone who knows far less then they think they do, pretending to know  far more than "everyone else".

For people who want (for whatever reason) silver nano particles, one MUST use a production method that controls the particle shape.

SilverSeas says...

Here is a link to one study that demonstrates that it is NOT wise to produce "tinier silver particles" via electrolysis. Those who attempt to try and re-invent the wheel really first need to do due diligence in research. This isn't the 1990's any longer, there is plenty of good science out there that supports the safety of EIS and calls into question other types of isolated silver products (like HVAC silver colloids, high particulate EIS, etc.):

i want silver generator sg7 in Botswana.please send me accessible number for easy communication,location aswell.

SilverSeas says...

Greetings, Mothusi:

Visit . Current contact information is always at the bottom of the page.

Mark S. (San Diego, California, US) says...

What about the Life Force EZ-1 Colloidal Silver Generator kit sold at Amazon? It has a 4.6 out of 5 stars on their customer review system. It is also cheaper than the models recommended here.

It looks very easy to use.

SilverSeas (Las Vegas, Nevada, US) says...

Hi Mark...

...lots of reviews due to good marketing skills and access to the Amazon market place!

This is nothing more than a simple "three nines" generator. The only thing nice about it is the magnetic stirring device.

You can make your own simple generator for MUCH cheaper.

If you are going to purchase a colloidal silver generator, why not purchase one that will make a superior end product?

SilverSeas (Las Vegas, Nevada, US) says...

There are a few more generators that we will be adding to this section in the future!
