Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 0.22 µm, 30 mm, 100/Pk - SF18284

Tisch Scientific welcomes bulk and blanket orders with volume discounts. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Cellulose acetate minimizes protein binding to maximize sample and analyte recovery while suiting aqueous solutions, buffers, and alcohols in routine use and stays smooth with low extractable background. The PP housing prevents sample bypass under rated operating pressure while routing flow to minimize backpressure in service and contributes minimal extractables to the filtrate. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Absolute pore-size rating gives consistent retention across protocols
• Very low protein binding supports high recovery of dilute samples
• Smooth surface with low extractables and a uniform pore structure
• Naturally hydrophilic surface wets readily with aqueous samples
• Sterile-grade retention at sub-micron pore sizes

Housing Specifications

• Rigid polypropylene body holds its shape under manual filtration pressure
• Thermal-bonded construction keeps adhesives out of the fluid path
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Resists aqueous acids, bases, and alcohols in routine sample prep

Sample clarification before injection is the cheapest insurance your chromatography system has. Pre-injection filtration protects the resolution your methods depend on so your retention times and peak shapes stay consistent.
