FS: a Robey Mark 1B Colloidal Silver Generator, $45 (or best offer). Colloidal Silver is useful for fighting infections of almost any sort; they are becoming more widely recognized and in demand, especially with the ongoing swine flu issue. The unit is ridiculously easy to use: just fill the glass jar with steam distilled water (not tap water), attach the jar to the unit, and it automatically turns on. The unit is placed out of direct light (incl. sunlight), and silver ions are generated approximately 1 part per million (ppm) for every minute the unit is left to run, e.g. if 15 ppm is desired, leave the unit alone for 15 minutes. The green light on the top of the unit turns on to indicate it is generating silver ions. It requires 3 9V batteries- 3 *new* 9V batteries are included and already installed in the unit.
This unit is in good used condition. The silver electrodes are not new but they are good for a great deal of use yet (new electrodes are only a few dollars anyway). Brand new, these CS generators go for $100. Google contains a trove of information on the subject, and taking properly-produced ionic Colloidal Silver is very safe.
This generator is priced competitively, and allows you to produce large quantities of good quality CS for pennies on the gallon, allowing this unit to pay for itself very quickly! Let me know if you have any questions. Thanks!
