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

Polyvinylidene Fluoride (PVDF) Membrane Filters, 0.22µm, 25mm - SF18130

Designed for the stringent demands of cell culture and biological assays, the Polyvinylidene Fluoride (PVDF) Membrane Filters offers validated bacterial retention for confident sample preparation. To achieve this medical-grade standard, the filter utilizes a Polyvinylidene Fluoride (PVDF) membrane that provides a sharp 0.22 cutoff necessary for sterilizing biological fluids. To ensure experimental consistency, the high-quality material provides uniform flow and predictable retention rates across the entire surface area. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

Key Polyvinylidene Fluoride (PVDF) Membrane Characteristics

• Polyvinylidene Fluoride (PVDF) membrane with hydrophilic (hplc) / hydrophobic (venting) affinity
• Ultra-Low Protein Binding characteristics
• Excellent resistance to HPLC mobile phases, alcohols, and mild hydrocarbons
• Incompatible with acetone, DMSO, or strong bases (> pH 12)
• 0.22 rating suitable for sterile filtration

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
