PTFE is an inherently hydrophobic membrane, excellent for filtration of organic-based, highly acidic or basic samples and solvents. Widely used in chromatography, it is especially well suited for the clarification of non-aqueous samples. Although this membrane

PTFE Laminated Membrane Filters, 0.45 Micron, 47mm, 100/Pk Product code PTFE04547100 The pore size refers to the diameter of the individual pores in a membrane filter. Pore size is typically specified in micrometers (µm).

PTFE Membrane Filters, Aspire Laminated, Hydrophobic, Polypropylene Backer, 5.0 Micron, 200x250mm, 5/Pk Product code 0QL2072005 The pores of microporous membrane filters act as small capillaries. When hydrophilic membranes come into contact with

Polytetrafluoroethylene (PTFE, Teflon) Membrane Information PTFE is an inherently hydrophobic membrane excellent for filtration of organic-based, highly acidic or basic samples and solvents. Widely used in chromatography, it is especially well suited for the clarification of non-aqueous samples.

Filter units with hydrophobic PTFE membrane are ideal for sterilizing gases, venting sterile containers, and sterilizing or clarifying organic solutions and protect your laboratory. Features Non-toxic, sterilized Aslo available through custom tubing packers

Verex Filter Vials are composed of two pieces: the external vial and the internal plunger with an integrated filter membrane (RC, PTFE, NY, PES, or PVDF) and cap. The unfiltered sample is first transferred into the external vial. Then the internal plunger with the

Phenomenex 13 For high load and particulate-laden samples you may consider placing a Glass Fiber (GF) pre-filter, either integrated with the membrane as one unit (Phenex-GF/NY or -GF/CA) or in series with the membrane syringe filter of your choice. Syringe

The Headline Membrane filter consists of a highly porous PTFE membrane in a stainless steel/PTFE housing with two bypass ports and inlet and outlet ports. The ports are designed to allow for permanent pipework, thereby enabling easy maintenance of the filter membrane.

Membrane solutions offers a range of various PTFE hydrophobic membrane applied for air filtration . Material characteristics of the PTFE hydrophobic membrane include high flow rate and long service life at low operating pressures,so they are ideal for sterile filtration and venting of air/gases.

Recommended filter membranes: Nylon 66® is a highly resistant material and can be used with almost all laboratory solvents. Since Nylon 66 is hydrophilic, no prewetting of the filter is required. PTFE (Teflon®)membrane filters are excellent for organic or other

Chemical compatibility is a critical consideration when selecting the proper sample prep syringe filter for your application. This chart outlines the chemical compatibility of the most common syringe filters. The contact time was 24 hours at 20 C. Syringe Filter
