PTFE Weaving Yarn. YEUMIFLON Weaving Yarn is a high performance fluorocarbon fiber with exceptional strength and good heat and chemical resistant for unusual applications. PTFE Staple Fiber. This fiber can be used to make felts mainly for the application in clearing up hot gases and gases containing chemicals.
PTFE is used as a non-stick coating for pans and other cookware. It is non-reactive, partly because of the strength of carbon–fluorine bonds, and so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant
Restek carries many accessories for SPE cartridges. To assure compatibility, simply match sizes across parts when ordering. For example, if 6 mL SPE cartridges are used, then 6 mL SPE accessories are needed, so part numbers 26012 (empty cartridge), 26018 (frits), 26003 (tube caps), and 26007 (connectors) are the correct items to choose.
Polytetrafluorethylene (PTFE) membranes are naturally and permanently hydrophobic. They are ideal for filtering gases, including humidified air. The extreme chemical resistance of PTFE membranes makes them very useful for filtering solvents or otherunsuitable.
Hamilton PTFE Tip, Gas-Tight Syringes. Suitable for gases or liquids. High accuracy of dispensed volumes. Interchangeable barrels, plungers, and tips extend performance and increase cost-effectiveness. Note: Syringes and needles sold by Restek are intended for scientific research and laboratory use only and are not intended for human in vivo or
polypropylene (PP) or polytetrafluoroethylene (PTFE) filters should be used. • For mixtures of organic and aqueous samples, PTFE, PP, nylon, regenerated cellulose (RC), and PES filters can be used, according to the percentage of aqueous/organic solvent.
chemical filtration. The hydrophobic PTFE membrane, combined with rugged HDPE supports and molded parts, enhances chemi- cal compatibility, controls contamination with low metal extract-able and particle shedding, and prevents cross-contamination of
2018/4/29 · The attachment of these hydrophilic nanoparticles onto/into the PTFE membranes will wet the membrane and decrease the hydrophobicity (or contact angle), letting solution penetrate the membrane pores. This will decrease the temperature difference between feed and permeate ( i.e ., driving force), since the thermal conductivity of aqueous phase was much higher than gas phase.
2017/10/15 · The structural integrity of the PTFE membrane was evaluated by exposing the membrane to ultrasonic vibration. Once again, its water SCA was not significantly affected ( Fig. 10 ). The SEM image of the treated membrane ( Fig. S2 in Supporting information ) shows that no fiber debris was found and the nanofiber remained intact, demonstrating a robust structural integrity against the ultrasonic vibration.
Filter both aqueous and organic solvents Optically clear when wet Hydrophilic PTFE membranes are a thin, unsupported, highly porous film that offers maximum chemical and pH resistance to a broad range of aqueous and organic solvents. This membrane exhibits high flow rates with minimal.

2018/8/7 · Polytetrafluoroethylene (PTFE) Membrane Hydrophobic, highly inert, and durable, PTFE is a popular material with a wide operating temperature range and resistance to the damaging effect of many chemicals. When should you use it? DO USE: for filtering
Protect pumps and machinery from aqueous aerosols PTFE membrane is a thin, highly porous film that behaves as an absolute retentive membrane. Their inherently hydrophobic nature make PTFE membranes ideal for applications such as filtering gases, aqueous aerosols, protecting vacuum pumps, or…
