CA Syringe Filter, 0.22 um, 25mm, Luer-Lok/Luer Slip, Sterile, 100/Pk
Tisch SKU: SF14493

Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SF14493

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 matrix stays stable across the pH 4 to 8 range while keeping protein adsorption very low across the run and accepts water-based reagents readily. The PP housing prevents sample bypass under rated operating pressure and holds extractables low for sensitive analyses. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Smooth surface with low extractables and a uniform pore structure
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• Very low protein binding supports high recovery of dilute samples
• Absolute pore-size rating gives consistent retention across protocols
• Sterile-grade retention at sub-micron pore sizes

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses
• Resists stress cracking from aqueous salt and buffer solutions
• Stable across the full aqueous pH range in routine sample work

Filtering particulates upstream protects the column investment your methods depend on. Reliable particulate removal protects your instruments and your data before each HPLC, UPLC, and dissolution run.
