Polycarbonate PCTE Membrane Filters
  • Low non-specific binding, translucent membrane with uniform, cylindrical pores
  • "Screen-type" membrane retains particles on the surface of the membrane, minimizing entrapment within the filter
  • Excellent chemical resistance with good thermal stability, non-hygroscopic and extremely weight-stable
  • Black and white membranes available; use for epifluoescence or electron microscopy, sterility testing

    Notes:
    1.Bubble Point is the minimum pressure required to force air through a membrane which has been prewet with isopropylalcohol
    2.Flow rate indicates initial flow rate at 10 psi using a KGS 47 filter holder:
         Water: using prefiltered (0.1μm) water
         Air: using prefiltered nitrogen
    3.Initial flow rate at 5 psi using a KGS 47 filter holder
