Millipore Durapore Filter 5 um PVDF 47 mm Total of 100 Filters

Millipore SVLP04700 Durapore 5.0 µm Hydrophilic PVDF Membrane Filters (47 mm Diameter, Pack of 100). High-purity, disc membrane filters engineered from hydrophilic polyvinylidene fluoride (PVDF) to deliver ultra-low protein binding, broad chemical compatibility, and high flow rates during particulate clarification and biological fluid filtration.

• MPN / Catalog Model: SVLP04700
• Manufacturer & Line: Millipore (Merck Millipore / EMD Millipore) / Durapore Membrane Filtration Series
• Quantity & Packaging: Pack of 100 non-sterile disc filters packaged in standard laboratory sleeve packs for controlled dispensing
• Membrane Material & Surface Chemistry: Hydrophilic Polyvinylidene Fluoride (PVDF); inherently wettable with water and aqueous buffers without requiring secondary wetting agents or pre-wetting with alcohols
• Nominal Pore Size Rating: 5.0 µm (optimized for coarse particulate removal, cellular debris clarification, and prefiltration protection upstream of critical 0.22 µm / 0.45 µm sterilizing-grade membranes)
• Physical Dimensions & Geometry: 47 mm circular disc diameter, flat sheet format with a smooth, plain white surface (non-gridded) for uniform cake formation and particulate observation
• Low Protein & Biomolecule Binding: Characterized by exceptionally low non-specific protein and drug adsorption (orders of magnitude lower than cellulose esters, nylon, or PTFE), maximizing analyte recovery in sensitive biochemical assays and biologics processing
• Chemical & Thermal Compatibility: Resilient against a wide variety of aqueous solutions, dilute acids, aliphatic and aromatic hydrocarbons, and select organic solvents; heat-stable and fully autoclavable (steam at 121°C for 20 minutes) or sterilizable via gamma irradiation and ethylene oxide (EtO)
• Hardware & Equipment Compatibility: Standard 47 mm diameter fits all standard 47 mm glass fritted vacuum filter holders, stainless steel funnel manifolds, in-line pressure filter holders (e.g., Millipore XX4304700, XX1004700), and reusable plastic filter funnels
• Primary Application: Clarification of biological fluids and tissue culture media, prefiltration of viscous serum and protein solutions, particulate analysis in hydraulic/aviation fluids, cell harvesting, and removal of large aggregates prior to chromatographic or spectrophotometric analysis
