OPTI-SEAL® piston seals are the longest lasting seals you can buy for use in aqueous/aqueous buffered mobile phases. Made from a proprietary UHMW-polyethylene-based material (ultra high molecular weight polyethylene), this seal material is more resistant to abrasion and wear than traditional PTFE-based seals (Polytetrafluoroethylene or Teflon).
ITB piston seals with graphite are superior product compared to other vendors' PTFE seals. Our proprietary PTFE-based Improved Teflon Blend (ITB) is designed to shed particles large enough to be trapped at the surface of 2µm frits, not embedded within them. ITB seals are the best choice for use in mobile phases with high organic content, or when the broadest possible solvent compatibility is required.
Optimize sapphire pistons offer optimal concentricity and resistance to wear. The angle at which sapphire rods are cut in relation to the grain of the crystal lattice has a large effect on the durability and strength of the finished product. This cut angle is tightly controlled during the machining process, resulting in a piston with maximal resistance to breakage and superior wear characteristics. Our sapphire rods are attached to ferrules using a proprietary process that provides maximum control over concentricity, an important parameter that has a direct effect on seal lifetime.
