CA Syringe Filter, 0.45um, 4 mm, Luer-Lok/Luer Slip, Nonsterile, 200 Pk
Tisch SKU: SF17509

Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 4 mm, 200/Pk - SF17509

Tisch Scientific customer service specialists focus on laboratory products and can help source the right solution for specific applications. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The cellulose acetate surface stays smooth with low extractable background and preserves dilute proteins in the filtrate. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use while keeping the fluid path low in extractable contamination and holds a reliable seal against the membrane edge. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

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

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Resists aqueous acids, bases, and alcohols in routine sample prep

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification keeps your sample preparation moving across the buffers and reagents your methods rely on.
