Merck Millex™-FG Syringe Filter Unit, Hydrophobic PTFE, 0.2 μm Features a hydrophobic Fluoropore™ (PTFE) membrane. Millex™-FG Syringe Filter, 0.20μm, Hydrophobic PTFE provides broad chemical compatibility and is ideal for filtering samples in organic solvents or to prevent back-streaming of atmospheric moisture in venting applications.

GVWP09050. Trade Name. Durapore ®. Description. Durapore® Membrane Filter, 0.22 µm. Background Information. Durapore® membranes provide high flow rates and throughput, low extractables and broad chemical compatibility. Hydrophlic Durapore® membrane binds far less protein than nylon, nitrocellulose, or PTFE membranes. Features & Benefits.

Chemical Compatibility Both filter types are biologically and chemically inert, and will meet extreme conditions of chemical compatibility and temperature. Fluoropore™ membrane is compatible with strong solvents, acids, and bases. (Exceptions are aromatic hydrocarbons at temperatures in excess of 80°C).

Overview of Non-Sterile Millex® Syringe Filters with Hydrophobic Fluoropore™ (PTFE) Membrane: • Ideal for filtering samples in organic solvents, and can also be used to prevent back-streaming of atmospheric moisture in venting applications. • Broad chemical compatibility and excellent solvent resistance with organic solutions

Our Fluoropore™ membrane is a hydrophobic, polytetrafluoroethylene (PTFE) polymer membrane bonded to a high density polyethylene support to improve the handling characteristics of the filter for normal applications. Fluoropore™ membranes provide broad chemical compatibility, high flow rates and consistency.

Description. Mitex™ PTFE Membrane is unaffected by almost all liquids, including organic solvents, concentrated acids and bases, propellants, and cryogenic fluids. Mitex™ membrane is unbacked, yet is easy to handle, combining the convenience of a backed membrane with the versatility of a pure PTFE membrane. Mitex™ membrane is hydrophobic.

PTFE Chemical Compatibility Chart: Polytetrafluoroethylene is very non-reactive and ideal for use with most chemicals.. Review the chemical compatibility of Teflon® and PTFE with various chemicals, solvents, alcohols and other products in the cart below.

Although chemical compatibility usually deals with the liquid phase of the sample, dissolved solutes may interact with the membrane in an undesirable manner. The solute of interest should not be adsorbed onto the surface of the filter. Most polymers used to make filters are highly adsorptive for biomolecules and will bind them out of the sample

In addition, solvent-membrane compatibility requires additional consideration of filtration specific factors. None of these published compatibility guides, for example, monitors the sol-vent's ability to wet a membrane or increase extractables. 4. This table does not consider solvent safety issues.
