Derek has strict requirements for the selection of purified water equipment suppliers. In terms of verification technology, Derek not only requires purified water equipment to comply with the 2010 edition of the Chinese Pharmacopoeia and GMP requirements, but also to comply with the standards of the US Pharmacopoeia and cGMP requirements. Korui's comprehensive strength in design, production, after-sales service, and successful cases ultimately won the recognition of customers.

In November 2013, Guangzhou Deruike Pharmaceutical Co., Ltd. Nanhai Branch finally reached a cooperation agreement with Shenzhen Kerui Environmental Protection Equipment Co., Ltd. after layer by layer screening of purified water equipment manufacturers.

Derui is a pharmaceutical company mainly engaged in research and development of pharmaceutical formulation technology, invested by Taiwan Fade Biotechnology Pharmaceutical Co., Ltd. The company relies on the scientific research strength of Sun Yat sen University and has a complete drug analysis laboratory and formulation pilot laboratory. The company's production base is located in the Dachong Industrial Zone of Nanhai Lishui, Foshan City, Guangdong Province. The products are the company's independently developed slow-release and controlled release formulations, striving to create the most advanced level of slow-release and controlled release formulation brands in China.

Derek has strict requirements for the selection of purified water equipment suppliers. Unlike in the past, in terms of technical strength, Derek not only requires purified water equipment to comply with the 2010 Pharmacopoeia and GMP requirements, but also needs to comply with the standards of the US Pharmacopoeia and cGMP requirements. In addition, considering the design scheme, production strength, after-sales service, and successful cases of numerous suppliers who initially meet the requirements, Korui stood out.
