Features of Iso-Disc Syringe-Tip Filters
Nylon Membrane: General filtration, especially for aqueous or other hydrophilic samples. Not recommended for use with acids.
PTFE Membrane: Gereral filtration for hydrophobic samples. High solvent resistance.
PVDF Membrane: Similiar to PTFE, but recommended where low portein binding is important.
0.45 Μm Pores: Most HPLC applications. 0.2 Μm Pores: Use when using 3 Μm HPLC columns or when suspended particles must be minimized.
