Pura Disc FP 30mm CA Syringe Filter, 0.45um, Sterile, 50 Pk
Whatman SKU: 10462100

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 30 mm, 50/Pk - 10462100

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. Cellulose acetate suits aqueous solutions, buffers, and alcohols while staying smooth with low extractable background and delivers absolute particle retention at the rated pore size. The polycarbonate housing stands up to rugged field and bench handling while supporting everyday aqueous filtration workflows and sustains high operating pressures without deformation. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

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
• Smooth surface with low extractables and a uniform pore structure
• Very low protein binding supports high recovery of dilute samples

Housing Specifications

• High-impact-strength housing resists cracking under demanding handling
• Sustains high operating pressures without deformation
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• 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 so column life and baseline stability stay predictable.
