In June 2013, Rayto Life and Analytical Sciences Co., Ltd. as a leading professional provider of medical testing equipment in China, decided to use the purified water equipment produced by Shenzhen Carrylean Environmental Protection Equipment Co., Ltd. after careful investigation and strict selection, which officially opened the door to bilateral cooperation.

Due to production needs, Rayto Company has decided to add purified water equipment that meets the 2010 GMP requirements. At the same time, the water quality of the produced water must also meet the purified water requirements of the 2010 Pharmacopoeia. The equipment is stable, reliable, energy-saving, and the investment cost is reasonable. This is also the direction that Korui is constantly striving for. The comprehensive competitiveness of Korui Company has been unanimously recognized by the relevant departments of Redu Company.
