The Best Colloidal Silver Generators
Retail Buyers Guide - Buying a Quality Generator

Welcome to our colloidal silver generator center, which has been designed to provide information on quality colloidal silver generators and the processes by which colloidal silver is made. In this section you can explore, review, and rate silvermedicine.org approved products and equipment.

...Silver in the News...

A Silver polymer which releases silver ions ( Ag+ ) was found to be effective against the SARS virus: “ We tested the compound against a four-hour, eight- hour, and 24-hour exposure period and found no surviving SARS virus upon 24 hours of exposure to the polymer...”             - Zhang Panhe, professor at the Chinese Academy of Military Medical Sciences Read More: Silver Ions Effective Against SARS

Colloidal Silver Generators: Electrically Isolated Silver (EIS)

Silvermedicine.org 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.
