Pura Disc FP 30mm CA Syringe Filter, 0.45um, Sterile, 500 Pk
Whatman SKU: 10462600

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 30 mm, 500/Pk - 10462600

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. The cellulose acetate surface stays smooth with low extractable background and suits aqueous solutions, buffers, and alcohols. The polycarbonate housing suits aqueous samples, buffers, and reagents while withstanding impact and handling without cracking and supports demanding high-pressure filtration. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• Absolute pore-size rating gives consistent retention across protocols
• 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

Housing Specifications

• 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
• Suited to aqueous samples, buffers, and reagents

Reproducible separations start with samples that reach the column free of particulates. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.
