1. Adopt a glueless bonding process to bond the PTFE membrane and silicone rubber or silica gel together to maintain the respective excellent characteristics of the two materials. The PTFE layer of the composite spacer has good contact with the reagent. It is chemically inert, resistant to acid, alkali, temperature, and adhesion. It does not interact with concentrated acids, concentrated alkalis or strong oxidants even at high temperatures. At the same time, the elasticity of the silicone rubber or silica gel layer can be used to ensure the sealing performance;
2. Adhesive-free process, without the introduction of adhesives, the septum retains the excellent resilience of silicone rubber or silica gel, which is softer than the adhesive process septum, and can provide better needles for the autosampler protection of;
3. Strict production management ensures the quality of the products. The product is clean and can be used directly without washing.
