MarvelX UHPLC Connection Systems from IDEX Health & Science maintain zero dead volume and prevent peak tailing. MarvelX UHPLC finger-tight fittings do not depend on ferrules, which significantly reduces required torque and enables many more connects and disconnects. Furthermore, they are virtually impossible to over-tighten by hand, which limits wear and increases product life. Enhanced high tech tip sealing also ensures zero dead volume (ZDV) and better chromatography results. Our PEEK-Lined system offers a truly biocompatible PEEK inner layer, serving as the fluid pathway, and is perfect for bio-inert UHPLC applications. Surrounded by a robust stainless steel structure, our durable PEEK-Lined connection system is rated at 19,000 psi (~1,310 bar) for routine use — with a maximum over pressure of up to 23,000 psi — and includes flexible tubing that can be replaced independent of fittings
