No-Met Biocompatible Mobile Phase Filters - Low Pressure

biocompatible mobile phase filter
  • Very competitively priced
  • Inert and biocompatible
  • Replacement filters
  • Also recommended for IC

Stainless steel in the flowpath is not acceptable in a growing number of applications involving the separation of biomolecules. High salt buffers can corrode stainless steel, and the metal ions released from metallic filters may contaminate or otherwise react with the biomolecules of interest.

The No-Met polyethylene filter is designed for these applications, with inert polymeric fittings for 1/8" tubing and a 20 µm filter effectively eliminating metal contamination from the fluid path. Use them for IC and biochromatography applications.

No-Met filters can be used at flow rates up to 500 ml/min, measured with methanol/water (1:1), ultrasonically degassed. Flow rates can vary with solvent and tubing ID.

The economy version can easily be slipped over 1/8" OD tubing, with no fitting required.

TECH TIP

  • Because they are hydrophobic, No-Met filters may initially require some priming with methanol or acetonitrile.
  • Connect the filter with 1/8" OD/ 1.59 mm OD tubing:
