This is the most popular size. It travels well in checked baggage.
Argentyn 23 represents the ultimate refinement and most significant breakthrough in colloidal technology, having consistently produced the smallest particles ever seen in colloidal silver products, with the most unique charge attributes (98% positively charged, called a "Hydrosol" of silver at 23 molar concentration). The manufacturing technique is proprietary but particle size and particle charge have been confirmed by third party laboratories and universities. Argentyn 23 does not use additives or stabilizers, nor does it contain salts or proteins (often used to keep silver in suspension, but which create silver compounds). It is pure, meaning it contains only 99.999% pure silver suspended in pharmaceutical-grade purified water. No other manufacturer can make these claims and support them with evidence.
