0.22 0.45 Hydrophilic PTFE Membrane Filters Manufacturer - Hawach. Description. Description. Hydrophilic membrane filter is permanently hydrophilized by low protein binding and has excellent chemical stability and high sample recovery. Hydrophilic membrane filters are widely used in HPLC and LC/MS/MS.
Fluoropore™ membranes provide broad chemical compatibility, high flow rates and consistency. (Please note that catalogue numbers containing "FHUP" are unlaminated, or produced without a backing.) Our Omnipore™ membrane is a hydrophilic PTFE membrane that is compatible with virually all solvents, acids, and alkaline solutions. Features
Hydrophobic PTFE Membrane Filters. Hydrophobic PTFE membrane filters are equivalent to Millipore, high performance with the extremely low background, the full range of pore size and diameter, small order acceptable. Hydrophobic PTFE membrane filters have OEM Service and customized size is available, round disc and roll type are on sales.
Feb 22, 2022 · Our filters are used for applications requiring 0.2 micron sterilization of air, gas, solvents and chemicals in life science industries. Validated PTFE Membrane Our LifeASSURE™ PFS series PTFE Filters use a hydrophobic polytetrafluoroethylene (PTFE) membrane, which helps minimize pore blockage from moisture in vent applications.
Jan 17, 2022 · Hydrophobic PTFE. These filters are highly porous, thin, and they behave as absolute retentive membranes. They remain inert even with strong bases, strong acids, and solvents which are chemically aggressive. You can use these membrane filters for sterilizing gases, venting gas and air, or for clarifying and sterilizing strong acids or solvents
Hydrophobic PTFE membrane filter is made of polytetrafluoroethylene ultrafine fibers by hot-melt bonding together. Difference from glass fiber membrane, PTFE filter is a kind of membrane material for deep filtration. Membrane filter disc has the following characteristics: membrane filter 0.22 μm is produced from food-grade isotactic polypropylene.
High-purity polypropylene and hydrophilic PTFE provide an economical alternative for the filtration of various MiE chemicals. The hydrophilic nature of the PTFE filter membrane does not require pre-wetting for aqueous based liquids typically necessitated with standard PTFE filter membranes.
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.
PTFE Membrane for Dolomite's Membrane Chip Interface. For use with Dolomite’s Membrane Chip and Membrane Chip Interface for effective separation of organic and aqueous solutions, in-line filtration and liquid-liquid contracting, the hydrophilic PTFE membranes offer excellent chemical resistance with a pore size of 0.2 µm.
Universal Hydrophilic Syringe Filters: Millex® Hydrophilic PTFE. Polytetrafluoroethylene (PTFE) is widely used in membrane filters due to its high chemical resistance and low protein binding. However, the native hydrophobicity of unmodified PTFE restricts its use to the filtration of organic solvents and solutions.
Syringe Filters - Tisch Scientific. Polypropylene (PP) syringe filters are designed for aqueous or organic solutions that have high levels of debris and for difficult-to-filter solutions. It's a hydrophilic membrane with a wide range of chemical compatibility with organic solvents. Pall Minispike Acrodisc Syringe Filters, Pall Life Sciences
Feb 15, 2022 · Nylon Net Filter, 20.0 um pore size, hydrophilic nylon membrane, 47 mm diameter. View Pricing. LSWP04700. Mitex ™ Membrane Filter, 5.0 µm pore size, hydrophobic PTFE, 47 mm. View Pricing. AP2504700. Glass Fiber Filter with binder, 2.0 um pore size, hydrophilic glass fiber with binder resin, 47 mm diameter.
Differences between hydrophilic membranes and hydrophobic membranes. A hydrophobic membrane, such as polytetrafluoroethylene (PTFE) will resist any aqueous sample, creating back pressure. Although it is sometimes possible to overcome this back pressure with additional force, there is a risk of membrane rupture and incomplete filtration.
