CA Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Sterile, 100/Pk
Tisch SKU: SF14494

Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SF14494

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. Cellulose acetate delivers absolute particle retention at the rated pore size and stays smooth with low extractable background. The polypropylene housing routes flow to minimize backpressure in service and stays inert across common laboratory solvents. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

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

Housing Specifications

• Rigid polypropylene body holds its shape under manual filtration pressure
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Thermal-bonded construction keeps adhesives out of the fluid path
• Stable across the full aqueous pH range in routine sample work

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 across routine and validated analytical methods.
