Advantec's line of unsupported, hydrophilic, pure PTFE membranes are ideally suited for use in HPLC separations and other applications involving mixtures of aqueous and organic solvents. Read More Choosing PTFE as a filtration medium ensures maximum chemical compatibility, wide-ranging thermal/pH resistance, and high flow rates/minimal aqueous extractables.

2018/8/7 · Membrane-sample Compatibility It’s easy to overlook membrane compatibility when picking out your filter or device for your sample filtration. Good membrane-sample compatibility supports efficient filtration and minimizes resistance, while poor compatibility might result in backpressure, ineffective filtration, or even chemical attack of your membrane, leading to contamination of your filtrate.

Thomson SINGLE StEP® Filter Vials Solvent Compatibility Chart R = ecommended. No significant change observed in flow rate or bubble R point of the membrane, nor visible indication of chemical attack. L = ed Recommended Use. Moderate changes in

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

Because of their low inherent levels of extractables, nylon membrane syringe filters are commonly used to filter samples that are intended for HPLC analysis. Nylon membrane syringe filters may not be suitable for all samples and are ideal for near neutral pH aqueous solutions and compatible nonaqueous solvents.

ADVANTEC. DISMIC® Disposable Membrane filter. Product Information. • Minimum sample hold-up : Unit housings are specifically designed to maximize sample recovery. • High purity : Non-pigmented housing and integral filter sealing assure that filtrates will not be adulterated due to pigment, dye, or adhesives leaching into the filtrate.

Acro® 37 TF Vent Device With PTFE Membrane. Multi-Purpose Filter for Small-Volume Venting and Gas Filtration. PTFE membrane and polypropylene housing have broad chemical compatibility. Disposable - Eliminates the cost and labor associated with disc

Hydrophobic PTFE Membrane Filters / Type 11806. The hydrophobic PTFE membrane filters are made of polytetra-fluorethylene (PTFE) only and are therefore permanently hydrophobic. Unlike hydrophilic filter types, they are not wetted by air humidity. Added to Shopping Cart.

Savana® PTFE Filters. Constructed with PTFE membrane and PP supports for enhanced durability and cleanliness. Hydrophobic Membranes. Hydrophobic version for air filtration, stripper and IPA or solvent applications in flat panel display or hard disk industries. Hydrophobic membranes do not require prewetting in solvent-based chemicals.

Gore-Tex is a brand of expanded PTFE (ePTFE), a material incorporating a fluoropolymer membrane with micropores. The roof of the Hubert H. Humphrey Metrodome in Minneapolis , US, was one of the largest applications of PTFE coatings. 20 acres (81,000 m 2 ) of the material was used in the creation of the white double-layered PTFE-coated fiberglass dome.
