What about normal phase pump heads (organic solvents)?

There is a special version for the 10 ml pump head (AZURA P 6.1L) that is optimized for the work with organic solvents.

For the 100 to 1000 ml pumps there is no special check valve needed. To work with

    • Aldehydes
    • most organic acids
    • Phenols
    • Ether (e.g. THF)

use the Kel-F / FFKM upgrade kits to extend the lifetime of your sealings.
