How to do better
Class 100 Cleanroom
From the first step at the beginning of the experiment to the last step of packaging, it is always kept in a sterile and purified environment.
Automated detection and regulation: Sterilization; air pressure; humidity; temperature; dust particles are automatically captured and regulated.
- Dual isolation
- HEPA air filtration
- Positive pressure space
- Automated Sterilization
- Dust particle monitoring
- Temperature and humidity regulation
Organic and Biological Dual Domain Technical Team
Our technicians come from the fields of organic chemistry and biology, and have mastered a variety of peptide synthesis methods, including solid-phase peptide synthesis, liquid-phase peptide synthesis, combined liquid-solid peptide synthesis, inverse solid-phase peptide synthesis, and microbial fermentation.
Quality control: Self-inspection as the core to promote the work.
Taking previous experience as an element of thinking and considering that it cannot be decisive for every production process, it has become an absolute code of conduct to insist on repeated testing throughout every process and to drive the next process with actual data as supporting evidence, which includes the analysis of particles in the environment; humidity; temperature; pressure; and purity; content; endotoxin; PH value; sterility in production, and so on.
Production facilities: peptide synthesis to lyophilization, from mg to kg
From mg of customized peptides for scientific research to kg of cosmetic peptides, we have all the precision equipment from synthesis; purification; preparation; lyophilization; testing.
