    Sapphire Piston for HPLC

  • Product Description
  • Sapphire Pistons are a consumable part of the HPLC pump and should be replaced on a regular preventative

    maintenance schedule. To maintain peak performance and avoid unplanned downtime, sapphire pistons require

    inspection every six months with yearly or as-needed replacement. Chonghong offers reliable and hard wear

    resistance sapphire piston,which is specifically cut in relation to the grain of the crystal lattice, yielding maximal

    resistance to breakage and superior wear characteristics. Attachment of the rod to the piston ferrule is performed

    through a proprietary process ensuring concentricity. This is an important, often overlooked procedure parameter

    that has a direct effect on seal lifetime.


  • Model :

Sapphire Pistons are a consumable part of the HPLC pump and should be replaced on a regular preventative

maintenance schedule. Sapphire pistons we made are inspected with a 10x magnifier or microscope to ensure

premature seal failure.

Now the sapphire pistons we are supplying in domestic are increaseling  replaced somemost of the  world famous

brand with economically in expenses and reliability in quality.
