Our PEEK-Lined Stainless Steel (PLS) Column Hardware is designed specifically for UHPLC bio inert applications. The PLS column hardware combines the strength of our stainless steel UHPLC column (IsoBar) with the chemical inertness of PEEK polymer to ensure the integrity of biological samples by minimizing unwanted surface interactions while also allowing operation under harsh solvent or pH conditions. This hardware has been designed for demanding applications within the UHPLC realm. The PLS column is available in a variety of standard lengths to accommodate various application requirements. Each column hardware design contains removable frits in Titanium and PEEK options. For custom lengths or frit porosities please contact us for more information.
