Pura Disc 25mm Dp PP Syringe Filters, 0.45um, 1000 Pk SKU: 6790-2504

Polypropylene Depth Filter (DpPP) Syringe Filters, 0.45µm, 25mm - 6790-2504

Streamline your sample preparation workflows with the Polypropylene Depth Filter (DpPP) Whatman Puradisc, 25mm, Depth Polypropylene Syringe Filter, 0.45µm 1000/pk, constructed to handle high particulate loads while maintaining rapid throughput. Facilitating rapid sample turnover, the hydrophobic Polypropylene Depth Filter (DpPP) membrane structure ensures the 0.45 rating remains consistent even under pressure. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

Key Polypropylene Depth Filter (DpPP) Membrane Characteristics

• Polypropylene Depth Filter (DpPP) membrane with hydrophobic affinity
• Low Binding characteristics
• Broad chemical compatibility with organic solvents
• Requires pre-wetting for aqueous solutions
• Verified 0.45 retention rating for clarification

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing

Hydrophobic

• Prefiltration - The robust depth of PP media allows it to handle high particulate loads before final membrane filtration
• Solvent Clarification - Polypropylene offers broad chemical resistance, making it suitable for filtering organic solvents
• Gas Filtration - Optimized for Hydrophobic PP membranes, which are excellent for venting applications and protecting vacuum pumps
• Chemical Processing - Ideal for filtering acids, bases, and aggressive solvents that would degrade other membrane types
• Quality Control Testing - Optimized for delivering reproducible results by removing particulates in standard pharmaceutical protocols
• Sample Clarification - Protecting analytical instruments via rapid removal of particulates to maintain high throughput in busy laboratories
