Tisch SKU: SF14487

Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SF14487

Tisch Scientific offers competitive pricing across its filtration catalog, helping cost-conscious laboratories keep supply budgets in check. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. The cellulose acetate membrane draws aqueous buffers through readily while preserving dilute proteins in the filtrate and delivers sterile-grade retention at sub-micron pore sizes. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use while keeping the fluid path low in extractable contamination and prevents sample bypass under rated operating pressure. 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
• Naturally hydrophilic surface wets readily with aqueous samples
• Smooth surface with low extractables and a uniform pore structure
• Absolute pore-size rating gives consistent retention across protocols
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8

Housing Specifications

• Resists stress cracking from aqueous salt and buffer solutions
• Medical-grade polypropylene with broad chemical compatibility
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Plasticizer-free polyolefin construction keeps the fluid path clean

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Upstream buffer clarification keeps avoidable particulates out of your flow path while keeping the filtrate analytically clean. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
