Hydrophilic PVDF Membrane Filters, 0.22 um, 25mm, Nonsterile, 200/Pk SKU: SF18130

PVDF Membrane Filters - SF18130

The Tisch SF18130 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. A uniform PVDF matrix maintains its rated 0.22 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. Controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Available in both hydrophilic and hydrophobic configurations, PVDF adapts to aqueous sample preparation as well as aggressive solvent venting applications.
• Inherent hydrophilicity enables immediate filtration of water-based samples without alcohol pre-wetting or surfactant conditioning.
• Mechanically robust and chemically resistant, PVDF provides reliable performance across a broad range of pH levels and solvent polarities.
• Stable performance at operating temperatures reaching 80°C ensures the membrane handles heated applications without pore distortion or structural compromise.
• Polyvinylidene Fluoride (PVDF) membranes combine broad solvent resistance with excellent mechanical durability across a wide range of pH levels and temperatures.

Environmental monitoring programs where sample-to-sample comparability determines trend validity benefit directly from the lot-level consistency of these membranes, removing the filter as a variable in your long-term data sets. Low non-specific binding on the PVDF surface ensures that analyte adsorption does not skew your results, which matters most when filtering dilute samples where even small losses affect quantitation. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

• Immunodetection Assay - Provides a high-sensitivity background for colorimetric detection, enhancing the contrast of faint protein bands.
• Fluorescence Imaging - Offers low background fluorescence, making it suitable for modern fluorescent western blotting detection systems.
• Protein Dot Blotting - Facilitates the rapid screening of multiple protein samples by applying them directly to the membrane grid surface.
• Colony Lifts - Transfers bacterial colonies from agar plates for hybridization screening, maintaining the exact spatial pattern of growth.
• Western Blot Transfer - The gold standard for protein transfer, offering high binding capacity and physical strength for immunoblotting assays.
• Binding Assays - Ideal for ligand-binding studies where the membrane's hydrophobic nature helps retain specific lipid-tagged molecules.
