Stainless steel frits

The analytical-scale 316 stainless steel frits from Biotech Fluidics are available in 0.5 µm or 2 µm porosity, which corresponds to the most common filtration ratings in HPLC. Each frit includes a polymer sealing ring made from PCTFE or PEEK. Many of the frits have the common 0.250” (6.35 mm) and 0.254” (6.45 mm) ODs, which allow them to be used in many of the guard column, precolumn and inline filter housings we also supply.

The frits for semi-preparative flow rates are available with 2, 5, 10, and 20 µm filtration porosities and a range of diameters to match your intended flow rate and filtration requirements. These frits come complete with a polymer sealing ring made from PCTFE, ETFE, or PTFE.

Note that faster flow rates may require larger filtration area and/or larger porosity. To minimize contributions from extra flow path volume, choose frits with a smaller diameter face and/or smaller porosity.

Benefits:

  • Available in porosity from 0.5 µm to 20 µm
  • Includes a polymer sealing ring
  • Fits many housings for guard columns and inline filters

Polymer sealing ring materials:

  • PCTFE = polychlorotrifluoroethylene
  • PEEK = polyetheretherketone
  • ETFE = ethylene tetrafluoroethylene
  • PTFE = polytetrafluoroethylene
