Permanently hydrophobic filter material, perfectly applicable for air and gas as well as non-polar liquids. PTFE membranes are characterised by an extraordinary chemical resistance versus nearly all chemicals and are suited for both filtration of acids or aggressive solvents and particle filtration of air or water samples up to 200° C.
LCR membrane is an unsupported, hydrophilic PTFE membrane compatible with all commonly used HPLC solvents. The membrane undergoes a special treatment process to remove any residual extractabes, ensuring that it will not add anything to your HPLC solvents, providing clearer analysis results.
PTFE filter becomes a hydrophilic PTFE membrane after treatment with ethanol or isopropanol. Applications of PTFE Filter. Membrane filter disc for filtration of anhydrous samples. PTFE membrane filter is used to sterilize gasses, vent gas from aqueous solutions, or sterilize or clarify aggressive chemicals.

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 - Available in several pore sizes (both hydrophilic and hydrophobic varieties) to suit your application needs
PTFE filter membrane, 47 mm diameter, 0.45 µm pore size, 100/pk 5191-4336 PTFE filter membrane, 47 mm diameter, 0.20 µm pore size, 100/pk 5191-4339 Nylon (polyamide) • Hydrophilic membrane suitable for particle removement of alkaline solutions and organic solvents • Nonsterile PTFE (polytetrafluorethylene)
Aug 30, 2018 · SEM images of the pristine PTFE membrane (a1-a3), the PTFE/PVA composite membrane (b1-b3), and the PTFE/PVA-GA composite membrane (c1-c3). The PTFE/PVA composite membrane without GA cross-linking and heat press is fluffy and sponge-like, and the electrospun PVA fibers are uniform with an average diameter of 189.8 ± 39.9 nm ( Fig. 2 b2).
• For aqueous samples, hydrophilic-type membranes are preferred, such as cellulose acetate (CA) or polyethersulfone (PES). • For organic samples, especially with aggressive solvents, polypropylene (PP) or polytetrafluoroethylene (PTFE) filters should be used. • For mixtures of organic and aqueous samples, PTFE, PP,
Hydrophilic PTFE membrane is optimized for low drug and protein binding with excellent throughput in typical aqueous and solvent sample preparation. High sample recoveries and low extractables provide for optimum analysis by HPLC and LC/MS/MS. The membrane is suitable for applications including natural product screening, aqueous solubility
Millex-LCR for Samplicity G2, 0.45 µm, hydrophilic PTFE, 33 mm, non-sterile This 33 mm syringe filter with a Hydrophilic PTFE membrane, for non-sterile filtration on the Samplicity G2 system, has a 0.45 µm pore size used in preparation of aqueous & organic solutions prior to chromatography or other instrument analyses.; find Millipore-SAMP2LCRB MSDS, related peer-reviewed papers, technical
The PTFE membrane failed to continue longer time than 23 h. Comparatively, the PTFE-PSA-1 membrane exhibited higher water vapor flux (~25.3 kg/m 2 h) while with salt rejection of 99.9% and long-term stability over 48 h due to the hydrophilic membrane surface with enhanced antiwetting property and water selective permeation. To assess the
