Placed immediately before the column, the precolumn filter traps particles introduced with the sample. For samples, which may irreversibly absorb onto the column, the use of guard cartridges is strongly recommended.

  • Protect columns from particulates, ultra low dead volume
  • Virtually no dead volume with no band broadening or loss of efficiency
  • Compatible with all HPLC columns
