Pura Disc FP 30mm CA Syringe Filter, 1.2um, Sterile, 50 Pk
Whatman SKU: 10462261

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 1.2 µm, 30 mm, 50/Pk - 10462261

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Syringe filters mount on a syringe to clarify a sample in a single manual pass. Cellulose acetate minimizes protein binding to maximize sample and analyte recovery while handling water-based samples and low-alcohol solutions and keeps filtrate clean ahead of analysis. The polycarbonate housing sustains high operating pressures without deformation and maintains integrity through the filtration run. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

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

Housing Specifications

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

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Upstream sample clarification keeps your separations clean and reproducible across your HPLC and UHPLC methods.
