Empty columns, XK series

Supplier: Cytiva

XK empty columns are designed for liquid chromatography at low to medium pressure. The user friendly design ensures trouble-free operation with fittings for direct connection to high performance liquid chromatography systems. They are compatible with aqueous solutions and most organic solvents used in liquid chromatography of macromolecules. They are not resistant to acetone, ktones, chlorinated hydrocarbons, aliphatic esters and phenol. Should be avoided: >10% NaOH, >10% HCl, >5% acetic acid and strong mineral acids.
