No-Met
Biocompatible Mobile Phase Filters

• Very competitively priced
• Inert and biocompatible
• Replaceable filters
• Recommended for IC

Stainless steel is not an acceptable material for a growing number of applications involving the separation of labile macro biomolecules. It is of great importance that all of the biological activity of the samples is retained and that the biological specificity remains unchanged. High salt buffer concentrations can corrode stainless steel and the metal ions released from these filters may react with the biomolecules of interest or even contaminate the eluents in ion chromatography.

To meet the needs of these applications, No-Met filters are designed from inert polymeric components which effectively eliminate metal contamination of the fluid path. The body can be either PTFE of polyethylene. Note that since the polyethylene filter is hydrophobic, it may require an initial priming with methanol or acetonitrile.

We recommend our 1/8" PTFE tubing for connecting all No-Met filters. The economy version, pictured at right below, can be easily slipped over 1/8" OD tubing, with no fitting required.
