Appendix B Solvent Compatibility
The O-rings and check valve ball, which are made from nitrile rubber (Buna-N), are
compatible with alcohols, aqueous buffers, and dilute aqueous acids and bases.
Typical HPLC solvents, such as dioxane, acetone, organic esters, ethers,
dimethylformamide, tetrahydrofuran, and concentrated acids and bases, can swell the seal
and check valve ball. Test for compatibility with questionable solvents by immersing these
components in a beaker of solvent overnight. Then examine for stability.
