Whatman
GD/XP Syringe Filter, Depth PP Filteration Medium, 0.45um (1500 pcs) SKU: 6993-2504

Polypropylene Depth Filter (DpPP) Syringe Filters, 0.45µm, 25mm - 6993-2504

Designed to protect sensitive chromatography columns from clogging, the Polypropylene Depth Filter (DpPP) Whatman GD/XP Syringe, depth polypropylene filtrationmedium, 0.45µm, 150/pk delivers exceptional retention of particulates without compromising flow rates. 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. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.

Hydrophobic

• 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
• Solvent Clarification - Polypropylene offers broad chemical resistance, making it suitable for filtering organic solvents
• Prefiltration - The robust depth of PP media allows it to handle high particulate loads before final membrane filtration
• Quality Control Testing - Optimized for delivering reproducible results by removing particulates in standard pharmaceutical protocols
• Environmental Monitoring - Ideal for removing particulates in water and wastewater analysis to ensure regulatory compliance
