Iso-Disc Syringe-Tip Filters

Sample filtration can prolong column life and minimize downtime. Use Iso-Disc syringe filters to protect your HPLC column and instrument. Filters are available in Nylon, PTFE, and PVDF.

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.
