20mm PTFE Septa

The PTFE layer of Aijiren’s 20mm PTFE Septa composite diaphragm is in contact with the reagent. It is chemically inert, resistant to acids, alkalis, temperature and adhesion. Even at high temperatures, it cannot work with concentrated acids, alkalis or strong oxidants. At the same time, the elasticity of the silicone rubber or silicone layer can ensure the sealing performance; Aijiren abides by strict production management to ensure the quality of the product. The product is clean and can be used directly without washing.
