The “Big Batch” Heavy Duty One-Gallon Sized Home Colloidal Silver Generator –This is our largest unit, and boy is it a beauty! It is designed specifically for people who need to make larger commercial-sized batches of colloidal silver quickly, easily and  effectively. Rather than making 16-ounce batches like the other units we offer, the “Big Batch” unit offers a significantly higher voltage-to-amperage ratio, allowing you to make one full gallon at a time of safe, pure high quality colloidal silver. In fact, thanks to the    special electronics it contains, it allows you to make a full gallon of colloidal silver in about the same amount of time required for our other units to make just 16 ounces!  Includes 2×9″ 14gauge silver rods
