Fluoropore^™, Mitex^™, LCR and Omnipore^™ Membrane Filters

Fluoropore™, Mitex™, LCR and Omnipore™ Membrane Filters Supported, unsupported and hydrophilized PTFE

Fluoropore Membrane Filters
Fluoropore membrane is a hydrophobic PTFE membrane bonded to a high density polyethylene support (FHUP has no backing).Fluoropore membranes provide broad chemical compatibility.


Mitex Membrane Filters
Mitex is an unsupported hydrophobic PTFE membrane. It can be used under extreme chemical or temperature conditions that other membranes cannot withstand (up to 260 °C).


LCR Membrane Filters
LCR is an unsupported hydrophilic PTFE membrane compatible with all commonly used HPLC solvents. It can be used to filter aqueous fluids without prior wetting. Available in syringe filters.


Omnipore Membrane Filters
Omnipore membrane is hydrophilic PTFE compatible with virtually all solvents, acids, and alkaline solutions (for HPLC solvent filtration, use LCR membrane).
