Pura Disc FP 30mm CA Syringe Filter, 0.8um, Sterile, 50 Pk
Whatman SKU: 10462240

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.8 µm, 30 mm, 50/Pk - 10462240

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. The cellulose acetate membrane keeps protein adsorption very low for accurate recovery and accepts water-based reagents readily. The polycarbonate housing suits aqueous samples, buffers, and reagents and stands up to rugged field and bench handling. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

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

Housing Specifications

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

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Reliable particulate removal protects your instruments and your data before each HPLC, UPLC, and dissolution run. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.
