Nanosep Centrifugal Devices w/ wwPTFE Membrane 0.45um, Clear, 500/Pk - ODPTFE04C35

Pall Corporation maintains the production controls and documentation standards established for regulated pharmaceutical and biotechnology applications. In a centrifuge, the wwPTFE membrane clears particulates from HPLC sample preparations. Inert wwPTFE maintains pore structure across harsh sample matrices while resisting aggressive organic solvents and accepts both aqueous and solvent samples. For HPLC sample preparation, water-wettable PTFE resolves the spin into a clean, injection-ready filtrate.

Key Characteristics

• Low hold-up volume preserves sample mass from limited-volume preparations
• Chemically inert across acids, bases, and oxidizers at working concentrations
• Water-wettable surface loads aqueous samples directly without pre-wetting
• Ultra-low UV-absorbing extractables keep HPLC and UHPLC baselines clean
• Fluoropolymer backbone resists acetonitrile, methanol, and aggressive solvents

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Upstream buffer clarification keeps avoidable particulates out of your flow path across routine and validated analytical methods.

• Solvent Sample Clarification - Clears particulates from acetonitrile, methanol, and mixed-solvent analytical preparations.
• Organic Matrix Cleanup - Removes particulates from aggressive organic samples without any membrane swelling or distortion.
• Aqueous and Solvent Prep - Clarifies both aqueous and solvent samples in one membrane without any pre-wetting or conditioning.
• Mixed-Solvent Clarification - Clears particulates from mixed aqueous-organic samples ahead of routine chromatographic analysis.
• HPLC Sample Prep - Clarifies solvent-containing samples before injection while keeping chromatographic baselines clean and steady.
• Low-Extractable Filtration - Clarifies samples while adding minimal UV-absorbing background to sensitive chromatographic detection.
