The COSILVER NANO 600 is a high end nano generator that is designed to produce superior and consistent ionic colloidal nano silver. Being fully micro-controlled, it is entirely automatic and very simple to operate. Just fill the glass vessel with distilled water to the mark, plug the unit in to the wall socket then and switch on at the wall. A red flashing indicator verifies that the distilled water is being converted into colloidal silver. It takes up to eight hours to complete the conversion process. If the power fails, just leave the unit plugged in and switched on. The NANO 600 has on board AI and will continue automatically when the power returns. We all know that good things come to those who wait. A blue indicator signals that the process is complete and that the crystal clear 16ppm ionic colloidal silver is ready. The COSILVER NANO 600 is perfectly safe to use and has a 100% duty cycle rating. This means you can use it continuously time after time for many many years to come.
