Characteristics: The super-thick even film of pure SiO2 makes a high-inert internal surface to keep good chemical stability and safety; Rare liquid solvent retaining on the internal wall thus greatly reduce the loss of pharmaceutical solvent; Solved the problems of metallic ion sensitive to the filling solvent, and pH-value easily increasing. It is applied for biologics, suspension agent, protein preparations, lyophilized preparations and costly antibiotics. Such product can also be used for chemicals researching to reduce the time.
