Pura Disc FP 30mm CA Syringe Filter, 0.8um, Nonsterile, 50 Pk
Whatman SKU: 10462241

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.8 µm, 30 mm, 50/Pk - 10462241

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The cellulose acetate membrane keeps protein adsorption very low for accurate recovery while staying stable across the pH 4 to 8 range and stays smooth with low extractable background. Strong polycarbonate construction supports demanding high-pressure filtration while resisting damage during demanding use and handles routine aqueous sample matrices. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Absolute pore-size rating gives consistent retention across protocols
• Smooth surface with low extractables and a uniform pore structure
• Very low protein binding supports high recovery of dilute samples
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• Naturally hydrophilic surface wets readily with aqueous samples

Housing Specifications

• Suited to aqueous samples, buffers, and reagents
• Sustains high operating pressures without deformation
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• High-impact-strength housing resists cracking under demanding handling

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.
