CA Syringe Filters w/ 3 Pre-Filters, 0.22 um, 25mm, Nonsterile, 100/Pk
Tisch SKU: SF18292

Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SF18292

Tisch Scientific offers competitive pricing across its filtration catalog, helping cost-conscious laboratories keep supply budgets in check. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The cellulose acetate membrane draws aqueous buffers through readily while delivering sterile-grade retention at sub-micron pore sizes and keeps protein adsorption very low across the run. The PP housing prevents sample bypass under rated operating pressure while routing flow to minimize backpressure in service and resists degradation from routine sample matrices. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• Absolute pore-size rating gives consistent retention across protocols
• Sterile-grade retention at sub-micron pore sizes
• Naturally hydrophilic surface wets readily with aqueous samples
• Smooth surface with low extractables and a uniform pore structure

Housing Specifications

• Resists stress cracking from aqueous salt and buffer solutions
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Stable across the full aqueous pH range in routine sample work

Reproducible separations start with samples that reach the column free of particulates. Pre-injection filtration protects the resolution your methods depend on so your retention times and peak shapes stay consistent.
