Pura Disc Aqua 30mm Syringe Filter, 0.45um, Sterile, 100/Pk
Whatman SKU: 10462655

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 30 mm, 100/Pk - 10462655

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. Across analytical workflows, the syringe filter is where particulates leave the sample stream. Low-extractable cellulose acetate keeps filtrate clean ahead of analysis and draws aqueous samples through readily. The polycarbonate housing holds a reliable seal against the membrane edge while sustaining high operating pressures without deformation and withstands impact and handling without cracking. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

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

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

Reproducible separations start with samples that reach the column free of particulates. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean.
