Tisch SKU: SF18293

Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SF18293

Tisch Scientific welcomes bulk and blanket orders with volume discounts. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. The cellulose acetate membrane keeps protein adsorption very low for accurate recovery 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 analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• 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
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• Absolute pore-size rating gives consistent retention across protocols

Housing Specifications

• Rigid polypropylene body holds its shape under manual filtration pressure
• Resists stress cracking from aqueous salt and buffer solutions
• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep

A clean particulate separation keeps your aqueous sample preparation dependable. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.
