Ultra Biphenyl Columns

"Biphenyl columns offer the HPLC performance benefits of a core-shell column with a unique stationary phase that will become go-to selectivity for reversed phase method development. While water may be hard for a C18 to handle, the Biphenyl column allows diving straight into the deep end with 100 % aqueous stability. Biphenyl column was designed to be your new go-to reversed phase column."
