Yes, the Output Current of the M250 model can be programmed for the treatment of yeast and fungal infections.

No. The SIS machines are not appropriate for the treatment of parasite infections.

No. None of the side effects known to be caused by antibiotics and antiviral drugs have ever been reported.

Additionally, none of the side effects of antibiotics were reported by the electromedicine pioneer, American orthopaedic surgeon Robert O Becker (1923-2008), nor by his research associates during their many hospital applications of silver-nylon cloth electrode iontophoresis or low intensity direct current (LIDC) treatments of infections and for tissue healing.

No. Zappers, Rife machines, and bioresonance devices are all electromagnetic frequency generating devices.

The SIS machine for infection treatments is a low intensity (amperage) direct current (DC) device; it does not have an Output Current or Output Voltage frequency, as it is a DC device.

The SIS machines for infection treatments have no functional or therapeutic similarity to any frequency generating device.

Typically, for a severe or acute infection, with (approaching) ideal 24/7 continuous use, we recommend replacement of the (+)positive electrode every 12-48 hours, and replacement of the (-)(‘return’) electrode every 24-48 hours. These guidelines can be modified depending on anatomical location and other factors such as ambient temperature that will affect sweating.

Further information and instructions for application of the SIS electrodes are included in the operating manuals of the SIS machines, and on the Instructions For Use card included in each SIS electrode pack.




No, the SIS electrodes are not sticky. They need to be held onto the body using standard adhesive medical fixation tape or other types of physiotherapy or injury rehabilitation tape. Bandages or other emergency means can also be used if necessary.

Fixation tape is a generally available, non-prescription item from any chemist or pharmacy, and from our SHOP >




Yes, but with caution and some restrictions. Refer to the WARNING below before attempting use. The SIS electrodes are only designed for use in the low microcurrent range and only with low voltages (maximum 5-10 Volts).

The SIS machines should not be compared to commonly available microcurrent stimulators, either electronically or therapeutically. These devices are not capable of the electronic requirements for silver iontophoresis or low intensity direct current (LIDC) therapeutics using silver-nylon cloth as electrochemical or electrical anode and cathode. The SIS machines are direct current (DC) devices; they have no output stimulation frequency. Most microcurrent stimulators are not DC devices: they are frequency emitting, pulsed waveform generating devices, similar to or actual alternating current (AC) devices.

For silver iontophoresis or low intensity direct current (LIDC) therapeutics using silver-nylon cloth electrodes acting as the (+)positive and (-)negative electrochemical or electrical anode and cathode for the release of silver cations (Ag+s) or for LIDC therapeutic effect, extremely stable ultra low amperage DC Output Current with nanoampere accuracy is required. This specification is beyond the capabilities of generally available microcurrent stimulators.

Additionally, the M250/M250MA/W250 model SIS machines are sophisticated realtime and statistical monitoring devices of the SIS silver-nylon cloth electrode↔skin contact. This function is also critical for silver iontophoresis or low intensity direct current (LIDC) therapeutics to occur over time at ultra low constant DC.



Yes, the M250 and M250MA SIS machines are ideal and very easy to use for colloidal silver production. The SIS machine electrode cable can be easily connected to widely available pure silver rods made specifically for colloidal silver production, using the set of Alligator Clip Cable Adaptors supplied with each SIS machine M250/M250MA model. The SIS electrodes can also be used in place of silver rods, though the rate of silver ion release will be slower.

The M250 and M250MA machines also have an automatic voltage polarity reversal function, which is very useful for colloidal (ionic solution) silver production. Periodically, the voltage polarity reversal ‘cleans’ electrochemical debris from the surface of the silver rods or SIS electrodes that builds up during use. This function can be manually disabled if required.

No, they are entirely different. Please continue to the link below to read about the SIS machine for infection treatments, or first read the information below.

Delivery of ingested silver ions inside the body

‘Colloidal silver’ (ionic silver solution), though certainly of use for surface infections, has limitations for the treatment of internal infections. The human body is often imagined as something like a bathtub of water: if you drop a substance into it, it will homogeneously spread out and automatically go everywhere. The body has ‘compartments’ and ‘barriers’, at every order of anatomical scale, down to the sub-cellular level. Silver ions, as with molecules of any medication, do not automatically reach a target area of infection.

Cellular binding sites and internal anatomical pathways

For ingested colloidal silver solution or spray, there are millions or billions of molecular binding sites available for the (+)positively charged silver (cat)ions, starting high up in the gastrointestinal (GI) tract, before they can reach an infection. Internal pathways are very complex and long. For illustration, the chances of getting a therapeutic dose of silver ions to a kidney infection might be very small. The silver ions must get through the stomach, where they can bind to the stomach’s hydrochloric acid and be used up, then go through at least part of GI tract, and eventually find their way to the renal (kidney supplying) arteries and into the inner compartments of the infected kidney(s). If they are not somehow transported or pass out through the walls of the intestines into the bloodstream, they must further be transported out into the circulatory system via the portal venous system route collecting blood from the intestines back through the liver, then back into the heart, in and out of the lungs, then back into the heart again, and finally into systemic circulation.

Inflammation hinders medication delivery

Localized inflammation of the target tissues can limit the delivery of any medication in general circulation. When inflammatory chemicals are increased in localized areas of infection or injury, they can cause mechanical, obstructing changes inside and around the smallest blood vessels (arterioles). Additionally, these arterioles can also become (chronically) constricted under the control of the smallest motor nerve fibers of the autonomic nervous system, resulting in a reduced amount of any medicine delivered via the bloodstream to those target tissues.

SIS technology approach

The operation and effects of the SIS machines does not depend on blood flow. Operating on the basic physics of electric voltages, electric currents and conductivity, a microorganism-specific low intensity constant direct current (LIDC) is delivered via the shortest possible route, directly to the target infection.

The SIS M250 version has also been designed for small scale water treatment and purification purposes.

We have not yet conducted an independent laboratory test of water sterilization. We therefore disclaim that we imply or have any data to support or confirm the usefulness of the SIS equipment for this purpose at this time. We intend to conduct the necessary assessment soon [target: 2021].

Yes. We provide full and ongoing support to the original purchase user of SIS equipment for its correct and optimal application. We will always communicate promptly and give as much help as necessary.
