Whatman
Pura Disc 25mm PP Syringe Filters, 0.45um, 50 Pk SKU: 6786-2504

Polypropylene (PP) Syringe Filters, 0.45µm, 25mm - 6786-2504

Streamline your sample preparation workflows with the Polypropylene (PP) Whatman Puradisc, 25mm, Depth Polypropylene Syringe Filter, 0.45µm 50/pk, constructed to handle high particulate loads while maintaining rapid throughput. At the core of the device is a uniform Polypropylene (PP) matrix, delivering high dirt-loading capacity and reliable exclusion of interfering particles. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

Hydrophobic

• Solvent Clarification - Polypropylene offers broad chemical resistance, making it suitable for filtering organic solvents
• Chemical Processing - Ideal for filtering acids, bases, and aggressive solvents that would degrade other membrane types
• Gas Filtration - Optimized for Hydrophobic PP membranes, which are excellent for venting applications and protecting vacuum pumps
• Prefiltration - The robust depth of PP media allows it to handle high particulate loads before final membrane filtration
• Research & Development - Supports protocols that need to remove particulates, providing the ability to protect analytical instruments
• Sample Clarification - Protecting analytical instruments via rapid removal of particulates to maintain high throughput in busy laboratories
