CA Syringe Filters w/ 3 Pre-Filters, 0.45 um, 25mm, Nonsterile, 100/Pk
Tisch SKU: SF18294

Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SF18294

Tisch Scientific offers competitive pricing across its filtration catalog, helping cost-conscious laboratories keep supply budgets in check. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. The cellulose acetate matrix stays stable across the pH 4 to 8 range and preserves dilute proteins in the filtrate. The polypropylene housing contributes minimal extractables to the filtrate while holding a reliable seal against the membrane edge and resists aqueous acids, bases, and alcohols. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

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

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Stable across the full aqueous pH range in routine sample work
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Resists stress cracking from aqueous salt and buffer solutions

Filtering particulates upstream protects the column investment your methods depend on. Upstream buffer clarification keeps avoidable particulates out of your flow path while keeping the filtrate analytically clean.
