HPLC column hardware

We design and manufacture analytical HPLC Vertex Plus column hardware ranging from 3 mm ID to 8 mm ID under strict quality control. For our high resolution 2mm ID columns, we use a special stainless steel column hardware with dead volume optimized frit technology. A special treated inner surface ensures consistent column packing and high column stability for all of KNAUER´s HPLC columns. A wide range of column lengths from 5 mm up to 300 mm are available. The easily exchangeable integrated precolumn for analytical columns is available upon request for all 3 mm ID up to 4.6 mm ID columns.
