RC - Hydrophilic regenerated cellulose membrane for aqueous and organic-aqueous liquids, i.e. polar and medium polar sample solutions.
PTFE - Hydrophobic polytetrafluoroethylene membrane for nonpolar liquids and gases; very resistant towards all kinds of solvents as well as acids and bases.
H-PTFE - Hydrophilised polytetrafluoroethylene membrane (hydrophobic with additional hydrophilic characteristic) for polar and nonpolar solutions; resistant towards all kinds of solvents as well as acids and bases.
MV - Hydrophilic cellulose mixed esters membrane with very low adsorption for aqueous or polar solutions.
CA - Hydrophilic cellulose acetate membrane for filtration of water-soluble oligomers and polymers; especially suited for biological macromolecules; very high stability in aqueous solutions.
PA - Moderately hydrophilic polyamide (Nylon) membrane for aqueous and organic-aqueous medium polar liquids.
PES - Hydrophilic polyethersulfone membrane for aqueous and slightly organic liquids; very low adsorption for pharmaceuticals and proteins; good stability against acids and bases.
PVDF - Hydrophilic polyvinylidene difluoride membrane for 100 % aqueous samples; water-soluble oligomers and polymers like proteins.
GF - Inert glass fiber filter with nominal pore size of 1 µm allows higher flow rates than small pore filters; for solutions with high loads of particulate matter or for highly viscous solutions (e.g., soil samples, fermentation broths). Also available as integrated prefilter combined with a specific membrane.
IC - Special filter for the filtration of aqueous liquids in ion chromatography. (For optimal results with blind values <5 ppb a pre-washing with de-ionized water is recommended).
Inlet/outlet: Luer lock female/Luer male.
