CHROMAFLEX® chromatography columns feature uniquely designed PTFE shielded o-rings to form a solvent resistant, leak-free seal. Each end fitting has a thin PTFE layer that is curled over the o-ring. Columns can be used with all aqueous buffers without modification and with organic solvents when the optional PTFE bed supports are installed in the end fittings and flow adapters. Columns also feature borosilicate glass barrel construction with PTFE end fittings and HDPE bed supports. Recommended sterilization is with ethylene oxide, 2N NaOH or 100% ethanol (autoclaving is not recommended).

Choose from standard or jacketed columns. Jacketed columns feature a water jacket around the barrel to provide thermal control of temperature-sensitive chromatographic separations. The jacket also acts as a safety shield.
