Ultradyne ® absolute-rated polytetrafluoroethylene (PTFE) membrane filters offer the highest level of assurance of chemical compatibility and filtration performance in aggressive chemicals, prolonged hot air service and other severe process conditions. Ultradyne ® filters’ PTFE membrane delivers superior flow rates and long service life.

Phenex Regenerated Cellulose (RC) Syringe Filters The Optimal Choice for Aqueous and Mixed-Organic Solutions Hydrophilic Regenerated Cellulose filter membranes are compatible with a very broad range of aqueous and mixed -organic solutions, making them one of the most universal filter materials used prior to chromatography. How It Works Document FAQ

The hydrophilic cellulose acetate membrane filters combine high flow rates, good chemical resistance (pH 4-8) and thermal stability with very low adsorption characteristics. They are excellently suited for use in pressure filtration devices.

Nov 16, 2021 · 50MM PTFE INLET SYRINGE FILTER: 50mm 0.22um or 0.45um PTFE Inlet Syringe Filters, Hydrophobic PTFE membrane is laminated with polypropylene. 50MM PTFE MAIN APPLICATION: Naturally hydrophobic PTFE membrane provides the best chemical resistance, and can be used forventing applications or filtering gases , individually wrapped filters.

The 0.5 μm pore size is normally used. Air and gas sterilization make use of the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 μm and 0.5 μm. Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm membranes.

Membrane filters are typically composed of polymers that have been chemically processed, resulting in highly porous thin films with microscopic pore structures. Membrane filters typically have absolute pore size ratings <1µm, with some exceptions.

Aug 7, 2018 · Cellulose Acetate (CA) Membrane. Hydrophilic filtration membrane with limited chemical resistance but made from pure cellulose acetate, which is very low protein binding and so excellent for protein recovery. Withstands temperatures up to 180°C, making it well suited for hot gases.

Phenex syringe filters are designed for efficient and rapid filtration of almost any solution prior to analysis, and are optimized for superior flow rates and high-throughput. Phenex offers a wide variety of membranes ideal for any application. High quality filtration product. Increased column lifetime.

PTFE membrane is highly chemically compatible for the filtration of harsh solvents that can destroy other membrane materials. PTFE is a hydrophobic membrane, so it will repel water and is not suitable for the filtration of aqueous solutions.

Phenex Polytetrafluoroethylene Syringe Filters The Optimal Choice for 100% Organic Solutions PTFE (Polytetrafluoroethylene) is an inherently hydrophobic membrane excellent for filtration of organic-based, highly acidic or basic samples and solvents.
