Description

Ks-Tek 20 mm Crimp Cap with Natural PTFE/Blue Silicone Septa (Silver) 100pk

The PTFE layer of the septum is in contact with reagents, has good chemical inertness, can resist acid, alkali, temperature, and adhesion. Even at high temperatures, it does not interact with concentrated acids, alkalis or strong oxidants. At the same time, it uses the elasticity of the silicone layer to ensure the sealing performance.
