Yes, this is the item you need if you have your own conventional, battery-operated colloidal silver system, and you want to make the jump to producing small-particle colloidal silver.
We've taken the basic pump product, and added these features:
36" of clear vinyl tubing installed
2 hose clips to make storing your tubing with the air pump simpler
Velcro strips on bottom so you may attach this unit to any existing conventional colloidal silver unit
2 "D" batteries installed
