The Story of Pure Copper DoorOpener

How we start and finished the manufacturing

Antimicrobial Activity of Copper

Copper ion’s oligodynamic action of metal can kill bacteria. The Japan Copper Development Association has been engaged in a variety of demonstration tests to scientifically demonstrate copper’s antimicrobial effect.

The tool’s material  is Pure Copper (C1100) which is tested and proved to kill the viruses.

In 1996, an aggressive O157 outbreak occurred, which resulted in a large drop in sales in the food service industry. Testing has demonstrated copper’s effects against O157.
In the tests, bacteria were cultured and observed in glass dishes in which 3 cm piece copper or brass plate was placed over agar containing O157. As a result, bacteria around the copper and brass plate were prevented from reproducing. The test also revealed that no bacteria had grown directly under the plate.
O157 is transmitted to humans throughout any season through ordinary food. We must not forget the danger of O157.（Japan Copper Development Association）
