PTFE membranes are naturally hydrophobic, and chemically resistant to all solvents, acids and bases. PTFE membranes do not impart any extractables to the filtrate. PTFE is an ideal membrane for transducer protectors, since it blocks water vapor and is also ideal for filtering and de-gassing chromatography solvents.
We are mainly engaged in producing premium quality Hydrophilic PTFE( Polytetrafluoroethylene) Syringe Filter made in China with cheap price. Please feel free to buy good quality Hydrophilic PTFE( Polytetrafluoroethylene) Syringe Filter in stock at a discount price from our factory.
Hydrophilic PES membrane consists of pure polyether sulfone polymers without support. It can provide good mechanical strength, thermal stability and broad chemical compatibility. It’s applicable for pure water filtration, particles removal of HPLC aqueous mobile phase, preventing column clogging.
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.
binding characteristics, RC membranes are an excellent choice for proteins, peptides and other biomolecules. Excellent general purpose/high-performance sample filter for most applications. PTFE is an inherently hydrophobic membrane, excellent for filtration of organic-based, highly acidic or basic samples and solvents.
