Pura Disc Aqua 30mm Syringe Filter, 0.45um, Sterile, 50 Pk
Whatman SKU: 10462656

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 30 mm, 50/Pk - 10462656

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Low-extractable cellulose acetate keeps filtrate clean ahead of analysis while suiting aqueous solutions, buffers, and alcohols and clarifies particulates at the rated pore size. The polycarbonate housing holds a reliable seal against the membrane edge while standing up to rugged field and bench handling and supports everyday aqueous filtration workflows. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Very low protein binding supports high recovery of dilute samples
• Smooth surface with low extractables and a uniform pore structure
• Naturally hydrophilic surface wets readily with aqueous samples
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• 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
• Suited to aqueous samples, buffers, and reagents
• Sustains high operating pressures without deformation

Sample clarification before injection is the cheapest insurance your chromatography system has. Pre-injection filtration protects the resolution your methods depend on by clearing particulates ahead of the column and frits.
