    Membranes


    Membranes enable a very convenient, fast and economical separation.
    Often they are also used as a neutral sample support for further analysis.

    Overview of available membrane filters
    Material Properties and pore sizes Type
    Cellulose mixed esters

    – suitable for aqueous solutions
    – also available sterile and/or
    with grid
    – recommended for gravimetric
    analysis
    – autoclaving possible at 121 °C
    – economical
    – pore sizes 0.2 – 0.45 µm

    		 PORAFIL® CM 
    Cellulose mixed esters,
    fabric-reinforced    		 – suitable for aqueous solutions
    – higher mechanical stability than
    PORAFIL® CM
    – pore sizes 0.2 – 0.45 – 0.8    		 PORAFIL® MV
    Cellulose nitrate – thermally stable up to 125 °C
    – autoclaving possible at 121 °C
    – pore sizes 0.2 – 0.45 µm    		 PORAFIL® NC
    Polycarbonate

    – very low halogen blank values
    – suitable for quantitative AOX
    determination
    – thermally stable up to 140 °C
    – pore sizes 0.4 µm

    		 PORAFIL® PC
    Cellulose acetate – suitable for aqueous and many
    alcoholic media
    – low protein binding capacity
    – thermally stable up to 180 °C
    – pore sizes 0.2 – 0.45 – 0.8 –
    1.2 µm    		 PORAFIL® CA
    Polytetrafluoroethylen (PTFE) – hydrophobic membrane
    – suitable for almost all solvents,
    chemical resistance towards
    acids and bases
    – for filtration of aggressive
    media

    – pore sizes 0.2 – 0.45 – 1.0 –
    3.0 µm    		 PORAFIL® TE
    Polyester
    		 – chemically very resistant
    membrane ( not as stable as
    PFTE)
    – suitable for TOC/DOC
    determination
    – thermally stable up to 150 °C
    – pore sizes 0.2 – 0.4 – 1.0 –
    5.0 µm    		 PORAFIL® PE
