BIOCERA Ceramic Balls are NSF 42 Certified and Recently Obtained NSF/ANSI/CAN 61 & 372
In the 1980s, Dr. Jeon Hyoung Tag researched with the Soviet, French, and American scientists on ruby sapphire crystal growth technology. Biocera Balls were created in the 1990s through Dr. Jeon's past researches on crystal growth technology. The process of manufacturing Biocera Ball includes a careful selection of raw materials and minerals that do not contain heavy metals. Afterward, a delicate procedure of temperature control results in the change of the crystal structures. Biocera has patents in Korea, United States, China, and other countries. The water-activated Biocera Balls are tested and certified at NSF international component for their material safety requirement only. (Component)
