This product is a high-quality pharmaceutical and medical rubber stopper laminated with a fluororesin film. By laminating a fluororesin film on the part that comes into contact with the drug, it suppresses interactions with the drug and provides excellent stability. Furthermore, it achieves the characteristics required for formulation applications, such as adsorption resistance, at a high level. It demonstrates its properties in various applications, including liquid and powder formulations, freeze-dried formulations, and infusion use. 【Features】 ■ Low adsorption ■ Chemical resistance ■ Low moisture absorption ■ Chemically inert ■ Gas permeability resistance *For more details, please refer to the PDF document or feel free to contact us.
