Welch Materials HPLC Column Welchrom C8, 5 μm, 2.1 x 125 mm

Welchrom uses the same UHP (> 99.999% pure) Type B silica found in all Welch silica-based stationary phases. We combine it with bonding and endcapping steps exclusive to the Welchrom products to produce phases with slightly different selectivity than Ultisil or Topsil.
