nanoEase from Waters is a synonym for capillary columns for HPLC and UHPLC. The connection of the capillary columns with an inner diameter of 75-150µm consists of a ZenFit connector, which is easy to assemble and fits into Waters V-Detail ports as well as into Rheodyne and VICI compatible valves. A capillary is already connected to this capillary column, which has an outer diameter of 360µm and is made of fused silica. For capillary columns with an inner diameter of 300µm, typical stainless steel hardware is used.
